Abstract
Air samples can be collected by a number of means and whole air sample collection in canisters or bags is one of the most frequently used options. However, whole air samples normally require preconcentration before analysis to achieve sufficient method sensitivity for trace components and the procedures are usually time consuming. This application note demonstrates that such a preconcentration for whole air samples can be done quickly with the solid phase microextraction (SPME) technique, which is fast, simple to use, low in cost, solvent free, and combines the sample concentration and introduction procedures for whole air samples into one single step. In addition to the improved sensitivity, the SPME also provides a better precision than direct injection of an air sample with a syringe.
