BioSECcurity² SEC System

For harsh analytical conditions at high salt concentrations and extreme pH values

Routine bioanalysis under harsh conditions has never been so easy and powerful. With the BioSECcurity² SEC system, PSS introduces the ideal solution for protein molar mass, purity, and aggregation analysis with advanced detection.

Problems in biopolymer analysis are often caused by corrosion due to the required high salt concentrations and the extreme pH values. In addition metal ions can lead to problems with the column lifetime or chromatographic artifacts.

BioSECcurity² overcomes these problems by offering a metal-free system. Matching PSS PROTEEMA columns with different particle sizes and the porosities 100 Å, 300 Å and 1000Å for the analysis of proteins are available in coaded bioinert hardware.
