Liquid chromatography pump calibration service

#HPLC, GPC/SEC and #Ionchromatography pumps need calibration of the flow rate they deliver on a regular base to maintain consistently accurate results. The traditional gravimetric calibration method, although accurate, has some operational challenges. TESTA has launched a new rapid response service that uses a real-time thermal flow sensor that is extremely accurate, sensitive, and high-resolution, to reliably calibrate the flow rate of Liquid chromatography pumps.

Consultancy for leading Polymer Institute.

The Institute of Polymers at the Bulgarian Academy of Sciences (IP-BAS) in Sofia has invited our Managing Director – Carlo Dessy to consult with them. IP-BAS are working with several systems from TESTA Analytical including a 200SM Research Goniometer system plus a NanoBrook tabletop Dynamic Light Scattering (DLS) and Zeta Potential unit. The goal of the visit is to discuss and help improve results obtained with both instruments, assess their operational status and provide training on the latest software packages for the two systems.

Design considerations for Refractive Index detectors

Is there such a thing as a universal refractive index detector for all instrumental techniques? A new informative technical note explains how the different measurement goals of HPLC, and GPC/SEC has led to the development of different optimised refractive index detection strategies for each technique.
