High sensitivity gas bubble monitor

High sensitivity gas bubble monitor.

Gas bubbles in liquid chromatography systems, can result in changes in retention times, pulsating baselines, unexpected changes in peak areas, irregular peak shapes, pump outages and excessively high back pressures. Likewise, gas bubbles in flow chemistry systems are a significant problem which can affect correct dosage of reagents resulting in a sub-optimal or unsuccessful reaction. TESTA has developed a new Solvent Line Monitor that provides constant feedback on the status of connected liquid chromatography or flow chemistry systems via an integral OLED display and offers optical and acoustic alarm as well as a digital output which might be used to stop a pump before a bubble can affect its operation.

High sensitivity device for detecting gas bubbles

High sensitivity device for detecting gas bubbles

Many HPLC and Ion Chromatography users will have experienced how #gasbubbles can result in changes in retention times, pulsating baselines, unexpected changes in peak areas, irregular peak shapes, pump outages and excessively high back pressures. Our new Solvent Line Monitor supports up to two optical sensors capable of detecting bubbles in real-time enabling constant feedback on the status of your connected chromatography systems. The new device offers optical and acoustic alarm as well as a digital output which might be used to stop a chromatography pump before a bubble can affect its operation.
