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.

Flowmeter Software Driver for Chromatography Data Systems

Including real-time flow rate data with each chromatogram is a valuable aid to achieving total quality assessment of any HPLC, UHPLC, LC/MS or GPC/SEC System.

TESTA Analytical has developed a powerful new software driver that allows control and collection of data from any of its AB-4XXXX Series liquid flowmeter using a chromatography data system (CDS) which supports the rc.NET Rapid Control framework.

Chromatography data systems typically include functionality that enables time-saving in the analysis, interpretation, and reporting workflows while technical controls ensure work quality, effective records management, and enhanced data security. Easy integration and full compatibility with these data systems is a vital requirement for any new device to be used with existing chromatographs by analytical labs that need the highest level of data integrity.

Automated software for HPLC pump validation

Validate the performance of your HPLC, uHPLC or GPC/SEC pump

The Pump Validation Software Suite is a powerful tool designed to provide, in conjunction with a TESTA Analytical AB-4000X range flowmeter, a fast and effective way to validate any HPLC, UHPLC or GPC/SEC pump. Capable of accepting raw data generated by the TESTA Analytical flowmeter PC-App, the Pump Validation Software Suite performs all necessary calculations automatically. All data and parameters are also automatically validated to assure their fitness for the task.

Refractive Index Detector

...for HPLC techniques

TESTA Analytical Differential Refractive Index (DRI) detectors are widely acknowledged as one of the most flexible high-performance detectors for liquid chromatography (HPLC and uHPLC) techniques. DRI detectors measure the refractive index of an analyte relative to the solvent. DRI's are considered to be universal detectors because they can detect anything with a refractive index different from the solvent.

Solvent Line Monitor

...for liquid chromatography techniques.

Running out of solvent when running an HPLC or any other liquid chromatography system is a problem most separation scientists will have encountered. Your chromatograph running out of solvent can lead to loss 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 Solvent Line Monitor is designed to eliminate this problem, without any user input or need for regular resetting. The Solvent Line Monitor runs independently and is fully compatible with almost any liquid chromatograph.

Another commonly experienced problem in liquid chromatography systems can arise from unexpected air or gas bubbles. The presence of bubbles or microbubbles can result in changes in retention times, pulsating baselines, unexpected changes in peak areas, irregular peak shapes, pump outages and excessively high back pressures. Connected to a liquid chromatograph pump feed line, the 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.

Multi-Angle Light Scattering detector (MALS)

...for HPLC techniques

If you are looking to determine absolute molecular weights of polysaccharides, proteins, and peptides or their aggregates by HPLC or uHPLC quickly and accurately, then look no further. Our BI-MwA MALS has the highest performance/price ratio of any light scattering detector used for molecular weight determination. Using the system allows you to eliminate column calibration and improve your data quality. The BI-MwA is simple to use but incorporates sophisticated research grade features.
