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.

For over 50 years, we have been continually striving to push the limits of quantitation for dioxins. But where do we stand today – and what’s our next plan of attack?

Though a recent paper about the data-distorting potential of gas chromatography in metabolomic studies is far from perfect, it does at least draw attention to the absolute criticality of robust experiment design – on both sides of the argument. And that’s got to be a good thing.

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.
