Chromatography

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.

Why Does Asparagus Make Urine Smell?

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

Why Chilli Peppers are Spicy

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

  • Workflow

    According to the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), it is necessary to test analytical methods for their linearity as part of a method validation study. The typical process for this is to prepare standards for five different calibration levels, and to make triplicate injections of each of these standards. more

  • How to analyze active unknown unknowns?

    More than ever, consumers are concerned about the food they consume. For example, for botanical extracts used in food products and food supplements, fraud is quite common. It is evident that specifications, quality control and regulation of botanicals need to be improved [1-3]. more

  • The Third Dimension

    Proteins play a fundamental role in our day-to-day lives. Thanks to proteins we can speak, move about and think; they protect us from disease and repair damage to our bodies. Proteins are also becoming more popular as active pharmaceutical ingredients: in 2012, the market share of biopharmaceuticals in Germany was 21% (figures from German-language report “Medical Biotechnology in Germany 2013”). more
