The analysis of flavour compounds in many industries is important for a number of reasons. This can include the differentiation between genuine products and those of lower grade materials produced using different ingredients; for quality control purposes to compare different production bat...

As available samples become increasingly active, and more complex, you simply cannot afford interferences caused by flow-path activity. A flow path that is not inert can cause peak tailing and signal loss. You can lose critical sample components, leading you to believe they are not present...

Mixed-mode chromatography is emerging as a powerful tool in separation of various molecules. Mixed-mode is defined as liquid chromatography in which at least two modes of interactions exist simultaneously, both controllable by mobile phase selection. In the last few years, several companie...

A relatively new application for ionic liquids, as solvents in static Headspace Gas Chromatography, is further investigated. Two ionic liquids were studied and the response towards a range of low boiling point residual solvents increased compared to when dimethyl acetamide was used as the...

Pesticide analysis is extremely important due to the need to ensure that foodstuff is not contaminated with pesticide residues, which can be harmful to human health. Pesticide analysis poses a number of challenges for laboratories due to the wide ranging chemistries within the contaminants...

This article discusses biologically important steroid measurements which have, in the past, seen a lack of analytical sensitivity. Examples include determination of testosterone levels in women and children and estrogen levels in post-menopausal women. The article gives insight into the an...
