the installation of MagIC Net 4.1.
With the new driver software, MagIC Net 4.1 can also be installed after theOMNIS Software has already been installed.

Defective conductivity detector￭

The message that appears when a conductivity detector is defective has
been made more precise.

Workplace program part
Importing/exporting sample data￭

Sample data can be imported and exported as CSV files with the Unicode
coding UTF-16BE, UTF-16LE and UTF-8. As a result, all characters are displayed correctly in the exported and imported files.
NOTICE

If the import format *.csv (Unicode) was defined in the old MagIC Net version under Workplace ▶ Sample table ▶ Properties... ▶ Data import,then a new import format must be defined by default in the new MagIC Net
version.
Select the same format for importing and exporting sample data.
If the export format is unknown and characters in the sample table are notdisplayed correctly, delete the file and re-import it using a different importformat.

Method program part
Displaying methods

8.0102.8014EN / 2022-09-27

3

￭

2 methods can be displayed and edited simultaneously.

Configuration program part
Audit Trail￭

If the audit trail contains a large number of entries, then the amount of data
may cause performance problems when opening the Audit Trail.
If the number of entries is monitored, then the Audit Trail contains a maximum of 500,000 entries. The amount of data does not cause any problems.
Metrohm recommends monitoring the number of entries.
If monitoring is not active, then a warning will now appear at 10 million
entries.

PDF not modifiable with 21 CFR Part 11 settings enabled￭

PDF files created in MagIC Net can be merged without requiring a password
using the Tools ▶ Options... ▶ PDF ▶ Modifying the document
allowed menu item.
However, this is possible only if the Settings according to 21 CFR Part
11 check box is not activated in the Security settings dialog underTools ▶ Security settings....

4 Fixed bugs
GeneralFile selection dialog￭

In the file selection dialog, the context menus of the file folders were notlabeled. The file selection dialog appears if you import data from or export
data to a memory location outside MagIC Net.
For example:– program part Database ▶ Tools ▶ Templates ▶ Export templates... ▶ New ▶ Target directory ▶ ... ▶ Select directory forexport– Configurationprogram part ▶ File ▶ Import... ▶ OpenWorkplace program part
"Bracketing" calibration mode￭Too many standards were used when calibrating with the calibration mode
Bracketing. The standards encompassing the sample in the sample tablewere used, as was correct. In addition, all standards that had already beenused for previous samples in the same sample table were reused, which waswrong.

Database program partReprocessing

48.0102.8014EN / 2022-09-27

￭

￭

￭

An error in connection with the regional Windows settings occurred during
reprocessing.
If the values 1 to 4 were used in a determination, then the determination
could not be opened in the reprocessing table for certain region-dependentsettings of the number formats.
For example: It was mandatory to use the decimal point as decimal separator.
Now all determinations can be opened, regardless of the regional numberformats.
In a method with multiple analyses, an error occurred when copying components. It was not possible to copy components and add them to anotheranalysis of the same method. The same error also occurred when copying
components in the Method program part (see "Method program part",
page 5).
Too many standards were used when calibrating with the calibration mode
Bracketing. The standards encompassing the sample in the sample tablewere used, as was correct. In addition, all standards that had already beenused for previous samples in the same sample table were reused, which waswrong.

Calibration curve properties￭

If the Response = f(concentration) function type was selected for thecalibration curve, then incorrect values were specified for Conc.(calc.) andConc.(dev.,%).

Database backup￭

In client/server systems, databases were not always backed up correctly.

Method program partCopying components￭

In a method with multiple analyses, an error occurred when copying components. It was not possible to copy components and add them to anotheranalysis of the same method. The same error also occurred during
reprocessing in the Database program part (see "Database program part",
page 4).

Formula editor￭￭The error function was not handled correctly. If there is an error, the numerical value 1 (error present) is generated. Instead, the numerical value 0 (noerror) was generated.
The function Error component name CONC was not executed correctly.
If the component was not calibrated, then an error should be displayed. If
there is an error, the numerical value 1 (error present) is generated. Instead,the numerical value 0 (no error) was generated.

Configuration program part
Adding columns

8.0102.8014EN / 2022-09-27

5

￭

If an automatically recognized column contained invalid characters, then
MagIC Net crashed when the Configuration program part was opened.
The column data is now checked for invalid characters before it is includedin the configuration. If a column contains invalid characters, it will not beincluded in the column table.

Archiving the Audit Trail￭

Once the Audit Trail is exported to a user-defined target directory, the directory is saved for future archiving. An error occurred if a non-existent target
directory was entered during renewed archiving and then theclicked next to the Target directory field.

5 Known bugs
GeneralMaximizing the window￭

If you are working with more than one screen and MagIC Net is not open
on the primary screen, then MagIC Net will be moved to the primary screen
when you maximize the window.
Workaround:– Drag the window to the desired screen.
The window automatically jumps back to the primary screen.
– Minimize the window on the primary screen.
– Press and hold [Alt] while simultaneously clicking on MagIC Net in
the task bar.
The window opens on the screen to which it was moved before minimization.
As an alternative to the workaround described, do not maximize the window, but simply make it bigger by dragging the margins.

Method program part
Statistics￭￭

An error is displayed if the CONCMEAN variable is used as statistics function.
Correct approach: Only use the CONC variable as statistics function. To
calculate the mean value, select the mean value in the Define statistics
window.
If the CONCMEANSD variable is used as statistics function, the results areoutput as invalid during reprocessing.
Correct approach: Only use the CONC variable as statistics function. To
calculate the standard deviation, select the standard deviation in the Define
statistics window.

Tandem dosing

68.0102.8014EN / 2022-09-27

￭Tandem dosing requires 2 dosing units. Dosing unit A doses until it is empty.
Then dosing unit A is filled. In the meantime dosing unit B doses. In thenext row, dosing unit A starts again with dosing. Each dosing unit dosesuntil it is completely empty and is then filled again. So it can happen thatboth dosing units are empty at the same time. If dosing cannot be carriedout correctly, the mixing ratio of the gradient changes. To avoid this, program the method in such a way that dosing unit B is filled in the beginning
or in the end of each determination.

Monitoring￭

Common variables cannot be used for monitoring. If common variables areused for monitoring as Upper limit and Lower limit in a method, thenthe limits in a running determination are invalid.

Database program part
Temperature specification￭￭

For 930 devices without oven, the Analyses tab in the Information subwindow shows a temperature of –22.8 °C.
If no column is defined for the analysis in a method, but a temperature isdefined for the device, then the Analyses tab in the Information subwindow shows no temperature. Therefore always assign a column to theanalysis.

Monitoring￭

A lower limit and an upper limit are defined for monitored determinations.
If the result is outside of the defined limits, then a message is displayed on
the Messages tab in the Information subwindow. If the determination isthen recalculated with changed limits and the result is within the limits,then the message will nonetheless be displayed.

6 Compliance
The current software version does not contain any modifications that affectconformity of MagIC Net regarding 21 CFR Part 11 or its classification into theGAMP software category.
