Enhanced Detector Stability Improves GPC/SEC Results

Enhanced Detector Stability Improves GPC/SEC Results. In standard GPC/SEC, after column separation, a concentration detector is typically used to record a signal proportional to the relative concentration of the sample. As most synthetic polymers are not UV active, a Differential Refractive Index (DRI) detector is commonly used for this task. A new technical note investigates how TESTA’s enhanced DRI detector can reduce baseline drift and improve the accuracy of results from any GPC/SEC system.

TESTA launch custom chromatography website.

For companies considering development of an optimized chromatography detector or instrument to solve an application challenge, improve their competitive position or enter a new market – we have launched custom-chromatography.com. The new site is packed with a wealth of useful information relating to TESTA Analytical’s rapidly growing OEM design, development and manufacturing service, our innovative technologies and happy customers.

Interested in Joining the TESTA team?

As a small growing company each person we add to our team must be mentally agile, willing to work hard and be adaptable to our evolving challenges. As a successful developer of new, innovative chromatography detectors and instruments for both end user and OEM customers our field of operation is challenging, but highly rewarding. An unconventional combination of different technical and problem-solving skills is what might lead to a career at TESTA Analytical Solutions.

Tasked with characterizing polymers or proteins?

If you are looking to quickly and accurately determine absolute molecular weights of proteins and polymers, then look no further! Our BI-MwA Multi-Angle Light Scattering (MALS) system has the highest performance/price ratio of any light scattering detector used for molecular weight determination. Using the system allows you to eliminate SEC/GPC column calibration and improve your data quality.
