7 Numbering of the units

7 Numbering of the units
If you set start parameters and time program commands, you have toselect the index of the respective unit.
The numbering of each unit depends on its position in the daisy chain.
The daisy chain defines how multiple modules are wired together insequence.
For 930/940/945 ICs this means: The upper unit always gets the number 1, the lower unit number 2 (for example for pumps and injectors).
For extension modules this means: Only 1 extension module can beconnected directly to the IC. The second extension module has to beconnected to the first and the third to the second. The numbering of
the units begins with the IC and continues with the extension modules
according to their position in the daisy chain.
For detectors this means: The sockets to plug in detectors are numbered. This number determines the index of a detector. Therefore, it ispossible that only 1 detector is connected but labeled as Detector 2
because it is plugged in socket 2.

NOTE
The numbering is fixed and cannot be changed manually.

NOTE
A sequence uses acquisition methods in the way they are when themethod is submitted. It is not possible to apply changes to the acquisition method during a sequence. Start a new sequence to apply changes
to the acquisition method.

8.2

Synchronizing events
Each module has its own time program. These time programs run in parallel but independently of each other. Synchronize time programs with thetime program commands Event Set, Event Wait and Event Reset.
Match different events by labeling them with the same name.
There are 5 predefined names that can be selected in the drop-down list.
It is also possible to define individual names.
￭￭￭

Event set
Event sets trigger actions in other time program commands. An
event set indicates the moment when another time program has to
execute its commands.
As soon as the time program reaches the line with the event set,other time programs can see the event set.
Event wait
An event wait is always looking for event sets with the same name.
If the event wait of a time program detects a corresponding event
set, then the time program executes the commands that follow after
the event wait.
Event reset
An event reset removes the corresponding event set. If you set an
event reset, then the event wait keeps on looking for the corresponding event set and does not execute subsequent time programcommands.

ExampleThis example describes the synchronization of 2 time programs with
events.
Both time programs start in parallel.
First, the sample processor transports the sample to the injector. Then the
IC injects and starts measuring, while the sample processor rinses the needle. Therefore, the time program of the IC must wait until the sample processor has transported the sample to the injector.

5 Event Set: Name=Loop Filled
This event set matches the event wait of the IC because both events
have the same name.
As soon as the time program of the IC reaches the line with theevent wait command, the time program of the IC starts looking forthe corresponding event set.
Now the IC starts executing the commands that follow the event
wait command.

Shutdown method
A shutdown method is an acquisition method with the purpose to shut
down the instrument.
In a shutdown method, the instrument executes the start parameters but
does not acquire data. Therefore, a shutdown method does not require atime program. A shutdown method cannot use information from thesequence table, for example the injection volume.
The USB flash drive contains a shutdown method (Shutdown
method_IC_Anions.amx). Import the shutdown method in the same way
as you imported the acquisition method (see chapter 8.1, page 23)

14 Parameters of the 941 Eluent Production Module

14 Parameters of the 941 Eluent Production Module
The 941 Eluent Production Module allows you to produce eluent for yourIC instrument from a concentrate and ultrapure water.
Thanks to the built-in Level Control, the module is capable of monitoring
the liquid levels in up to 4 liquid containers with level sensors.

14.1

Level sensor modes
With the 941 Eluent Production Module, you can either monitor or produce eluent. These options are determined by the presence of an 800
Dosino.
You can use a level sensor in full mode or empty mode. These options are
determined by the rod length.
Each combination of Production/Monitoring and Full mode/Empty mode ispossible.

Metrohm IC Driver for OpenLab

Production Full
An 800 Dosino is configured for the level sensor. The level sensor isequipped with a short rod.
Eluent production takes place continuously. The production stops assoon as the defined eluent volume is produced or the liquid container
is filled.
Production Empty
An 800 Dosino is configured for the level sensor. The level sensor isequipped with a long rod.
Eluent production takes place in a batch process. If the liquid container
gets empty, then the ongoing run is completed. After completing therun, the defined eluent volume is produced and the module waits until
the waiting time has elapsed. Then the next run starts.
Monitoring Full
No 800 Dosino is configured for the level sensor. The level sensor isequipped with a short rod.
The level sensor monitors the fill levels in liquid containers. A warning
occurs as soon as the liquid container is full.

OpenLab distinguishes between 2 kinds of data acquisition.
￭￭

Single sample analysis
Only 1 sample is analyzed.
Sequence
A series of samples is analyzed.
A sequence contains parameters of the run, for example sample type,acquisition method, processing method or injection source. These
parameters can differ for each sample.
NOTE
Due to a bug in OpenLab 2.3, it is not possible to run single samples
with an instrument that contains 2 ICs. With an instrument that contains 2 ICs, you can only run sequences.
(Tracking Number: CDS2ACQ-13525 250249)
This bug has been fixed in OpenLab 2.4. In OpenLab 2.4, it is possible
to run single samples with an instrument that contains 2 ICs.

To create either a single sample analysis or a sequence, go to Acquisition ▶ Home. Click on [Single Sample] or [Sequence].

If you load a method, then the Metrohm IC Driver for OpenLab checks
whether the configured hardware corresponds to the instrument themethod was written with.
It is possible to load a method that was written on an instrument with adifferent configuration. In this case, the Metrohm IC Driver for OpenLab
resolves the differences between the instruments in the following way:
￭

￭

￭

If the configured instrument contains fewer modules than the instrument from the loaded method, then the entire modules are removed
from the method.
If the configured instrument contains more modules than the instrument from the loaded method, then the additional modules are added
to the method. The start parameters are set to their default values.
Adapt the start parameters if necessary. The time program is empty.
If the configured instrument contains fewer units than the instrumentfrom the loaded method, then the start parameters of the missing units
are removed. A warning occurs in the time program if a time programcommand uses a non existing unit. The user has to resolve this difference manually by deleting or adapting the affected time program command.
If the configured instrument contains more units than the instrumentfrom the loaded method, then the default start parameters of the additional units are added. Adapt the start parameters if necessary.
NOTE
If you write a method and change this method on an instrument with adifferent configuration afterwards, then the following behavior occurs:
The parameters for the modules of the first instrument are still stored in
the background of the method. If you load the method in an instrument with the same configuration as the first instrument, then theparameters that were defined in the original method are used again.

Metrohm recommends to configure the instrument with automaticconfiguration.
If you configure the instrument automatically, then the stirrer is deactivated by default. If you want to use the stirrer, then activate the stirrer
in manual configuration of the 858 Professional Sample Processor (seechapter 5.2, page 12).
If you configure an instrument with a 941 Eluent Production Module
automatically, then no level sensor is configured by default. Configure
the rod length of the level sensors manually (see chapter 5.5, page15).
If you configure your instrument with manual configuration, configure
the instrument in the following order:– 930/940/945 IC– 858 Professional Sample Processor– 889 IC Sample Center– 944/947 Professional UV/VIS Detector Vario– 941 Eluent Production ModuleThis is the same order as in automatic configuration. The order is relevant because you can only load a method if it was written on an instrument with the same order of modules.

The number of a detector refers to the number of the socket where
the detector is plugged in. The number of a detector does not dependon the actual number of connected detectors. If the instrument contains 1 detector that is plugged in socket 2, then the detector is labeled
as Detector 2.
If you want to use a Remote Box as an MSB device, you have to configure the Remote Box for the 930/940/945 IC. It is not possible toselect the Remote Box as an MSB device for the 858 Professional Sample Processor.
A high-pressure gradient can only be configured for 940 Professional

It is not possible to execute a time program that contains the command Measure Conductivity several times for the same conductivity
detector.
Only the first Measure Conductivity command is executed. All subsequent Measure Conductivity commands are invalid. These commands are ignored but no error occurs.
For the 858 Professional Sample Processor and 889 IC Sample Center,you cannot define a recording time or post time. Therefore, ensure thatthe recording time and post time of the IC time program is longenough to cover all time program commands of the 858 Professional
Sample Processor and the 889 IC Sample Center.
If the time program of the 858 Professional Sample Processor takes
longer than the defined recording time and post time, the time program is stopped after the defined time.
The position type Next Vial from Sequence of the 858 Professional
Sample Processor and the 889 IC Sample Center can only be used if
the next sample uses the same acquisition method as the current sample. Ensure that the sequence in the sequence table meets the requirements of the Next Vial from Sequence command.
Metrohm recommends to use shutdown methods without time program and with a recording time of 0 minutes.
If you use a method with time program as a shutdown method, then
the time program is executed in the shutdown method. Time programcommands that use information from the sequence cannot be used in
the time program of a shutdown method.
Do not use the following commands in the time program of a shutdown method:– Dosing units commands – Volume mode: Injection volume– Dosing units commands – Volume mode: Injection volume next
sample– Move – Position type: Vial from Sequence– Move – Position type: Next Vial from Sequence– Move – Position type: Vial from Sequence +1– Event Wait
With instruments with a detector, it is not possible to execute a run
without data acquisition. Always add a measure command to the time
program. Otherwise, the instrument stays in the state Injecting anddoes never enter the state Run.
If you do not want to acquire data during the run, then add a time
program command Measure Conductivity at the end of the time
program and define a recording time of 0 minutes. As different detectors in an instrument can have different recording times, ensure thatthe recording time for each detector is properly adapted.
If an instrument does not contain a conductivity detector, then the
instrument enters the Run state with the first acquisition command. In
this case, the command Measure Conductivity is not needed.

If you create a single sample analysis or a sequence, you must select aninjection source. If you want to use the vial position that is defined in
the sequence, then select the following injection source:– With an 858 Professional Sample Processor, select IC -Injection
Valve or Sample Processor.
– With an 889 IC Sample Center, select Sample Center - Injection Valve.
An error occurs if you select the injection source External or No
Injection/Instrument Blank and the time program command Vialfrom Sequence, Next Vial from Sequence or Vial from
Sequence +1.
If you create a single sample analysis or a sequence, you must select aninjection source. If you want to use the injection volume that isdefined in the sequence, then select the following injection source:– With an 858 Professional Sample Processor, select IC -Injection
Valve or Sample Processor.
– With an 889 IC Sample Center, select Sample Center - Injection Valve.
An error occurs if you select the injection source External or No
Injection/Instrument Blank and the time program command Injection volume or Injection volume next sample.
For Agilent instruments, you can run a pretreatment program for sample preparation. The pretreatment program is executed before theactual time program.
For Metrohm instruments, a pretreatment program does not exist.
It is not possible to change the acquisition method during a run. If you
want to change the acquisition method, finish the run, change theacquisition method and start a new run.
While you run a sequence, it is not possible to edit the next line of thesequence.

If a leak is detected during a sequence, the current sequence is aborted. The next sequence is started. At the start of the first run, the driver
checks whether the instrument is still leaking. If the leak still exists, thesequence is also aborted. The driver repeats this procedure until all
sequences have been aborted or the leak has been removed.
The moment when a time program starts measuring is displayed with a
red line in Online Signals. If 2 detectors of a 2-channel instrument
start measuring at a different time, then the following behavior applies:
In the charts for the conductivity detectors, both of these moments arerecorded at the same time. Actually, only the measurement for 1 detector starts at the recorded time. The measurement for the other detector starts later.
In online signals, it is possible that the time axes of different signals do
not coincide.

Data analysis￭

Metrohm IC Driver for OpenLab

In contrast to MagIC Net (the IC software from Metrohm), noise anddrift of the conductivity detector are not measured in the time program. Noise and drift are determined with System Suitability Calculations. To calculate noise and drift, select Signal to noise in theprocessing method.
Refer to the OpenLab Help for further information System Suitability
Calculations: How To ▶ OpenLAB CDS ▶ Data Analysis ▶ Calculations and Background References ▶ System Suitability Calculations.

22 Troubleshooting
Instrument errors
If an error occurs during equilibration or during data acquisition, send themethod to the instrument again. If the error persists, search the activitylog (see "Log files", page 113). If necessary, send the log files to yourMetrohm representative (see "Log files", page 113).
Connection problems
In case of connection problems, proceed as follows to establish a stableconnection:
Reconfigure the instrument
1 Close the instrument connection with [Close Connection].
2 Optionally delete the instrument and create a new instrument (seechapter 4, page 5).
3 Configure the instrument again with automatic configuration (see"Automatic configuration", page 7) or with manual configuration(see "Manual configuration", page 8).
4 Launch the instrument again.
Establish a new connection
Before executing this procedure, close OpenLab CDS, remove allconnected modules from the PC and shut down the PC.
1 Start the PC.
2 Plug in the required modules.
3 Switch on the modules one after another.
4 Check whether the modules are available in the Windows Device
Manager. This connection is mandatory.

22 Troubleshooting

5 Start OpenLab CDS and configure the instrument (see chapter 5,
page 6).
Several instruments on 1 PC
Execute this procedure if there are several instruments on 1 PC and the
instruments do not get idle.
1 Close the instrument connections with [Close Connection].
2 Launch the instruments one after the other.
3 If the instruments still do not get idle, close the instrument connections again with [Close Connection].
4 Launch the instruments one after the other again but change thelaunching order compared to the last attempt.
5 Repeat steps 3 and 4 until the instruments get idle.
NOTE
Especially with the 944 Professional UV/VIS Detector Vario, connection
problems may occur.
If you try to reconnect the instrument after switching off the power orafter disconnecting the USB plug, then the module is often not available in the Windows device manager.
Log files
If a problem with your instrument occurs, then the activity log or the
Metrohm log contain further information about the problem.
The activity log contains messages about errors and activities, for example
executing parameters. The activity log states whether the logged activities
were executed successfully or not. In case of a failure or an error, theactivity log provides tips on how to solve the problem or possible reasonsfor the failure or error.
