BIOTECH SOLVENTLINE MONITOR

The next generation programmable, highsensitivity bubble and “Empty-Bottle” detector

Designed to eliminate common problems
Running out of solvent during operation of an HPLC or any other liquid chromatography system
is a problem most separation scientists have encountered. Running out of solvent can lead toloss of data, need to re-prime the pump / system downtime and often necessitates system
re-validation to make sure the obtained results are within expected limits.
The Biotech Solvent Line Monitor is designed to eliminate this problem, without any user input orneed for regular resetting. It runs independently and is fully compatible with any liquid chromatograph.
This simple-to-use device will constantly monitor the status of the feed line of up to two
chromatograph pumps (very handy when gradients are involved) and trigger an alarm if an“Empty Bottle” is detected. Set-up is via an intuitive PC-App which allows individual settings fordifferent attached pumps. Further to an acoustic alarm, the Solvent Line Monitor also provides
a relay contact which can be utilized to stop a pump or to forward the alarm condition to the PC
Software used in your liquid chromatography system.
Connected to a liquid chromatograph pump feed line, the Biotech Solvent Line Monitor will
non-invasively check the status of liquid flows for air / gas bubbles and stop operation if any
are detected thereby, increasing the performance reproducibility and reliability of any liquid
chromatography or flow chemistry system.
The presence of bubbles or microbubbles can result in changes in retention time, pulsatingbaseline, unexpected changes to peak area, irregular peak shape, pump outage and excessively
high back pressure. As a result of these problems, accuracy and precision can decline to thepoint where analytical scientists may be unable to distinguish between trace amounts ofanalytes they are trying to detect and the system baseline.

If you want…
… To avoid air related pump breakdowns… To stop unreliable results due to air bubbles… To be able to rely on your HPLC, GPC/SEC or Ion
chromatography system…then choose the new Biotech Solvent Line Monitor!

Technical information
The AB-41001 Solvent Line Monitor is specifically designed to detect the status of the liquid
content in a transparent or translucent tube feeding a liquid chromatography system. Twodetectors can be connected to the main unit at the same time, allowing detection of two different
flow paths. The sensors are simply clipped onto the tubing without any need of modification orinteraction with the tubing content.
The Solvent Line Monitor is compact in size and is powered via a USB connection. PC based
software app allows easy configuration of the device when connected to a liquid chromatographor flow chemistry system. The Solvent Line Monitor App provides an unattended “listener”
service displaying chromatograph alarm settings status on your PC monitor. In “gas bubble
detection mode” – the status of the monitored chromatograph pump tubing is also displayedon the Solvent Line Monitor’s high-resolution OLED display.
The Solvent Line Monitor supports up to two optical sensors capable of detecting bubbles
in any transparent or translucent PTFE, Tygon® or similar tubing materials commonly used inHPLC, Ion Chromatography and GPC/SEC systems.
The device provides constant feedback on the status of connected sensors via an integral
OLED display and offers optical and acoustic alarm as well as a digital output which can beused to stop a pump before a bubble can affect its operation. The compact and easy-to-use
Biotech Solvent Line Monitor is programmable in terms of sensitivity, mode of operation andalarm reaction. System set-up is a straightforward process using a highly intuitive PC-based
app included with each device. Detection parameters including the minimum size, frequency
and number of bubbles can be configured using the PC App, which also provides facility fordifferent actions to be taken once an alarm status is detected. Examples include a simple beepor a stop signal to a connected pump.
