µFlowmeter

Precise measurement of liquid flow to ensure reliable, quantitative LC/MS

The AB-40004 microflowmeter (µFlowmeter) from TESTA Analytical is an affordable non-invasive device optimised to provide continuous high precision measurement of low volume liquid flows that may be split off for analysis from chromatography systems. Fully compatible with all organic and aqueous chromatography solvents, the AB-40004 µFlowmeter is the perfect tool for precise measurement of liquid flow to ensure reliable, quantitative HPLC/mass spectrometry (LC/MS) measurements.

Liquid Chromatography Flowmeter

Real time monitoring of chromatography system flow rate.

Traditionally the quality of analytical data from HPLC systems has been determined by periodic checks of a set of measured parameters. This unfortunately just gives you a snapshot of how your HPLC system is performing at a point in time and cannot assure the total quality of an application.

Our Liquid Chromatography Flowmeter (LCF) is an intelligent real-time monitoring device for continuously measuring the performance of pumps serving HPLC and uHPLC systems opening the door to the world of total quality assurance.

By monitoring the liquid flow being delivered to your HPLC system in real-time, the TESTA Analytical LCF generates a constant stream of data which is easily correlated to a particular chromatogram, thus achieving true total quality assurance of your application. Compatible with all HPLC solvents, the compact LCF powers itself from a USB connection. This non-invasive device will operate over a wide dynamic range.

Detects undissolved gas bubbles in real time.

Chemistry Flowmeter

Dissolved gases are well known to have an impact on the performance of reagent dispensing pumps. A common solution to address this problem is to install a vacuum degasser on the inlet side of the pump. However undissolved gas bubbles will pass through largely unaffected by the degasser which can lead to unreliability in dispensing volumes. Several companies are now using the Solvent Line Monitor to detect undissolved gas bubbles in real-time. In these installations, the digital output from the device detecting an undissolved gas bubble is being used to stop the dispensing pump before it can negatively affect dispensing accuracy. As a result of implementing the Solvent Line Monitor, these organizations have improved the product quality and yield from their production processes.

Chemistry Flowmeter

Improving accuracy and repeatability of chemical reactions.

Designed to be fully compatible with most solvents, acids, and bases – the Chemistry flowmeter sets a new standard for continuous, non-invasive measurement of the flow rate from pumps being used to add liquid reagents to batch or flow chemistry reactions. Without accurate flow measurement, too much or too little chemical can be injected into a reaction. Also, if the rate of addition of reagents is not constant this can also result in adverse outcomes, expensive reagent overuse, lower final product yield and safety issues.
