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.

Flowmeter Software Driver for Chromatography Data SystemsIncluding 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.

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.
