Backed by decades of experience, Testa Analytical has created a range of high-performance HPLC, GPC/SEC and Chemistry detectors, pumps, accessories and software products customizable to meet your exact needs. Our team of knowledgeable technical and engineering staff are available to discuss your needs and to provide seamless integration of our technology into your existing or new product.

Here are some examples of projects we have undertaken:


Liquid Chromatography FlowmeterReal 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.

µFlowmeterImproving 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.

Refractive Index Detector Kits...for HPLC techniques.

A high-performance Differential Refractive Index (DRI) detector is widely acknowledged as one of the most flexible detectors for liquid chromatography use. A DRI is a detector that measures the refractive index of an analyte relative to the solvent. They are often used as detectors for high-performance liquid chromatography (HPLC) and gel permeation /size exclusion chromatography (GPC/SEC). DRI’s are considered to be universal detectors because they can detect anything with a refractive index different from the solvent.

Based on decades of experience in the field, TESTA Analytical Solutions designed a DRI Detector adaptable to fulfil the specific demands of different clients. The key to this versatile detector is based upon modularity of the DRI kit from which it is designed.

Remote Cell Rapid Scanning UV Detector KitTESTA Analytical Solutions has introduced a remote cell option for its Rapid Scanning UV Detector kit allowing this elegant technology to be integrated into a wider range of industrial applications.
The Remote Cell option allows users to separate the measurement cell from the Rapid Scanning UV Detector kit using optical fibers up to 1000 mm long. This innovation enables highly accurate remote UV analysis to be made on process samples even under harsh process conditions that would make direct measurements almost impossible.

Refractive Index Detectors are most commonly utilized to identify compounds with no UV Absorbance. As such, they find application in GPC/SEC for Differential Refractive Index Detectordetermination of polymer concentration but also very frequently are used for the detections of sugars and polysaccharides. The DRI Differential Refractive Index Detector shows excellent performance and sensibility and can be found in R&D and QC labs worldwide.
