Specific techniques of extraction for organic pollutents analyzed with gaschromatoraphy

The proper choice of a measurement technique is only one step in the development of a sucessful application. All steps leading up to the measurement are equally important. The sampling and the samplepreparation process begins at the point of collection and extends to the measurement step. The sample preparation method used to convert the sample into a form suitable for the measurement step can have a greater effect on the overall accuracy and reability of the results and the measurement itself. Sample preparation is one of theimportant problem in analytical process.
