Gel Permeation Chromatography (GPC) is widely acknowledged as one of the most useful characterization methods able to provide a complete picture of the natural or synthetic polymer sample under investigation. A new technical note describes how the design of TESTA’s unique Differential Refractive Index (DRI) detector has been improved to provide reduced baseline drift and thus improve overall GPC system performance improving accuracy of results.

We have developed a new software tool for our AB4000X range of flowmeters to enable labs to automatically validate pump flow to liquid chromatographs and flow chemistry systems. Using this powerful new software tool - all data and parameters are automatically validated for fitness of use for validation and a summary report generated which can be printed for hard copy documentation.

A new Standard Operating Procedure (SOP) is available detailing how to use your TESTA flowmeter as a liquid chromatography monitoring device. Flow rate is one of the most important parameters in any liquid chromatography system. It determines retention time or volume and therefore has a major influence on reproducibility. Our popular liquid chromatography flowmeter has set a new standard for non-invasive measurement of flow rate in HPLC, uHPLC and GPC/SEC systems. This new SOP was written to take the guesswork out of day-to-day flowmeter operation and help ensure that all users can get the most out of this real-time monitoring device.

Just 5 years ago we started building a thriving social media community. Since May 2018 - we have set about regularly posting new and informative content relevant to the liquid chromatography market that we serve. We are delighted to say that in June we reached our landmark 1000th follower. Thanks to all of you in our social media community for following us on LinkedIn, Twitter, Facebook and Instagram. To help build our community further we’d be delighted if you would share some of our posts with your fellow separation scientists.
