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.

Understanding all processes and reactions inside the lithium-ion battery in detail is essential for its further development. Especially interphases, which strongly influence the performance, safety and service life of energy storage systems, are still insufficiently investigated. They are particular more
Simulated moving bed chromatography (SMB) is a process chromatography technique that allows you to continuously separate the molecules from binary mixtures into two fractions. Chiral compounds, carbohydrates and cell culture products can be separated much more effectively than with batch HPLC due to more
The purification of proteins should be simple and reproducible with as little hands-on time as possible. Often, a high degree of automation and high throughput is desired without compromising flexibility to purify now and then in a different way. And at the end of the day, who wants to risk destroy more
It is a major challenge to extract high-purity active pharmaceutical ingredients (API) from natural products at high yields. This applies also to the cannabinoid sector. Simulated moving bed (SMB) chromatography sets the benchmark for productivity, purity and yield in the continuous processing of ch more
The chromatographic purification of natural substances is often a challenge due to the complex starting materials. The silicafree alternative more
In recent years, the advent of Ultra High Performance Liquid Chromatography (UHPLC) has broadened the scope of laboratory applications, making it more

The sensitive determination of sugars and other carbohydrates is important for many applications. UV or fluorescence detection, which are widely used in HPLC, cannot be used without additional derivatization and detection via the refractive index can often be too insensitive. In this webinar, you wi 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

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
In analytical sciences one of the major goals is to develop and validate methods for the identification and quantification of molecules in complex samples to support investigations in the pharmaceutical sciences, environmental sciences, food sciences, biology and medicine. more
Impurity testing is an essential part of pharmaceutical quality control because toxicity and content of impurities contained in drug products can impair patient safety. This requires suitable, validated analytical methods. more
