Abstract
An apparatus and its method of use are described for the preparation of samples for organic material analysis, especially for gas chromatographic analysis. The samples in question are samples of organic materials (usually in trace quantities) which have originally been dissolved in water. In the process and apparatus of the present invention each sample is initially transferred to an adsorbent material from which it is in turn transferred to an organic solvent (which may be subsequently dried) and collected and from which the chromatographic analysis sample can later be withdrawn.
