Technical Tip: Static Headspace Sampling
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. |
