Data Analysis

The pursuit of the metabolome may no longer be a novel field, but it remains the biggest analytical challenge.

This application note describes the use of a Zetasizer Nano ZSP to characterize the charge state of spidroins in different formulations. The earliest stages of spidroin aggregation in different formulations are then assessed using low-temperature synamic light scattering (DLS) thermal trend experiments.

A sample of PMMA was analysed by Size Exclusion Chromatography with Triple detection, before and after sterilization. Reduction in the molecular weight was shown to be firstly by cleaving the polymer at the branching points.

In this application note, a selection of proteins are separated using Size Exclusion Chromatograpghy (SEC). The molecular weights of their oligomers and aggregates are measured by SEC-MALS and the results discussed.

Triple detection GPC/SEC combines measurements from multiple detectors to offer not only increased amounts of data, but also increased amounts of information, which is made available by the combination of different detectors (and unobtainable using individual detectors separately). The theory of triple detection GPC/SEC is described here.

This application note describes the analyses of a variety of aqueous (water-soluble) cellulose derivatives using the OMNISEC triple detection system and the subtle, yet distinct differences between these different derivatives that can be parsed out by the OMNISEC system
