The most important thing about chromatographic separation processes, whether gas, thin film, liquid chromatography or HPLC, is the clean separation of a mixture of substances. Here the application, whether preparation, quantitative or qualitative analysis, is of minor importance. Some columns deliver true top performance even under very high pressure.

The idea for this graphic came to me whilst saving the chilli peppers from a forlorn looking, aphid-infested chilli plant that’s probably on its metaphorical last legs. I thought it would be quite interesting to look at the origin of the heat in chilli peppers, and how this can be quantified. A fami more
When validating a method according to the ICH guidelines, it is necessary to perform a linearity experiment. This requires the preparation of multiple calibration levels, analysis of the samples by liquid chromatography, and calculation/reporting of the results. Each of these steps can be very time

In 1871 the children‘s book “Through the Looking-Glass – And What Alice Found There” by the English author Lewis Carroll, in which Alice enters a world behind the mirror, was published. She explains to her cat: “First there’s the room you can see through the glass – that’s just the same as our drawing room, only the things go the other way. …How would you like to live in Looking-glass House, Kitty? I wonder if they’d give you milk in there? more
What kinds of contaminants are enriched in sediment – and are these then absorbed by the organisms that live there? What role do microplastics play? To answer these questions, Professor Gesine Witt’s team is using pollutant samplers made from silicone-coated glass fibre to investigate the sea floor. And not just as research for research’s sake but because the protection of our environment is a top priority. more
