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 analysis of oils, fat and fat contain- ing food containing food via fatty acid methyl esters (FAME) is a common task in governmental, quality control (QC) or contract research laboratories (CRO). Most often the samples are processed manually, whi more
As demonstrated here, there are a broad range of HPLC applications used in development, production, validation and release of protein therapeutics for human use. Some of the applications mentioned above are mandatory when submitting a new biopharmace more
The latest food chemistry graphic looks at the chemistry of asparagus – specifically, why it causes the urine of some (but not all) people to smell. Over the past forty years several papers have been published on the subject, and several studies undertaken, to try and determine the chemical compound more
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

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
Geoscientists, biologists and chemists at the University of Tübingen are working in collaboration with IFAM (Fraunhofer Institute for Manufacturing Technology and Advanced Materials in Bremen, Germany) to uncover the workings of insect surface adhesion. The goal of this project is the synthesis of an adhesive based on insect secretions. 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
