INTRODUCTION
Large volumes of solvents including chloroform, ether, benzene, toluene, among many others are utilized in most laboratories for the extraction and concentration of various components in samples for subsequent analyses. New methods which reduce or eliminate the solvents required for sample purification provide many advantages to the laboratory. The exposure of laboratory staff to these solvents has become of major concern to both employees and health officials. The disposal of used solvents has become a serious problem and is rapidly becoming quite expensive. In addition, a sensitive and accurate analysis of residual solvents in the final product is necessary because of both toxicology and quality control. The new Short Path Thermal Desorption System permits the direct thermal analysis of samples without any prior solvent extraction. Samples to be analyzed are inserted directly in the Glass Lined Stainless Steel (GLT) Desorption Tubes and held in place with two quartz wool plugs. The Desorption Tubes can then be inserted in the Short Path Thermal Desorption System and heated to the desired temperature to vaporize the residues and solvents within the samples. A constant carrier gas flow through the sample will then flush the vaporized residues into the injection port of the gas chromatograph (GC) for subsequent analyses.
