In an ideal chromatographic separation, all sample components would be isolated from each other and detected as fully resolved peaks. However, it is not uncommon to encounter some degree of overlap. In extreme cases, what appears to be a single peak contains in fact two or more coeluting components. This article discusses how to check the purity of such peaks in order to correctly interpret the results of the analysis.

They say a picture paints a thousand words…This month I’ve taken inspiration from a recent webcast, presented at www.chromacademy.com, in which I presented real data from our work that represents some ‘classic’ GC problems.

Static headspace sampling is typically used for the determination of volatile and semi-volatile analytes in liquids and, more rarely, solid matrices. Application examples include the analysis of alcohols in blood, residual solvents in pharmaceuticals, flavours and taints in food and beverages as well as fragrances in perfumes and detergents.
