Innovative column technology for liquid chromatography Fast, efficient and cost saving chromatography of various samples by application of a liquid stationary phase. Termination of disadvantages of the solid phase material used in classical chromatography....
Do you see the complete picture? "Triple Detection" in Gel Permeation Chromatography Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact that by the separation process the whole molecular weight distribution is obtained. The molecular weight distribution contains much larger information for the characterization of polymer samples compared to a single value....
Half a Century of Chromatography with Agilent and Predecessors One Century of Chromatography with Twsett (1903) Twsett originated the chromatography with his work about the separation of chlorophyll in 1903. For some time it was relatively quite around this new technology. Exceptions were the workings of Kuhn and Lederer (1931) as well as of Hesse (1936 and 1942). A break through succeeded to E. Cremer during the 40ies, but hardly considered caused by the war events, what however in the years 1950/51 by the conception of the gas chromatography suddenly changed and involved a rapid development...
SRI Gaschromatographs: "Customized GC" since 1986 Since 1986 SRI Instruments Inc. (Las Vegas) develops gas chromatography systems with the main objective to build an instrument which can easily be adapted to the customer's needs. The result was a modular built GC which can be equipped with up to six different detectors to cover a wide range of analytical methods...
From Sephadex to GE Healthcare The success of chromatography as a technique for separating biomolecules is inevitably linked to the introduction of the gel filtration medium Sephadex(TM) by Pharmacia AB in 1959...
