MODERN SOLUTIONS
The variety of samples, and analytes, delivered daily to analytical laboratories is huge.
Unfortunately, there is no universal method of preparing samples for analysis on the
market. Dealers of analytical solutions try to meet the growing demands and introduce
to analytic new extraction techniques that increase the efficiency of sample preparation
process, as well as reduce the cost of a single analysis. Disposable pipette extraction is
used for preparation of different kinds of samples, including biological, environmental
and food samples prior analysis by gas and liquid chromatography. Enrichment of volatile
and semi volatile organic compounds in liquids and solids might be performed by stir bar
sorptive extraction. The dynamic headspace analysis is very effective extraction technique
dedicated to analysis of volatile substances responsible for the taste and smell of food
products as well as for determination of fragrance in household products.
