英文摘要	a sol-gel coating-method for the preparation of coating film on bars used in sorptive microextraction is described. the poly( dimethysiloane) (pdms) is partially crosslinked with the sol-gel network, and the most. part is entangled within the network. three step aging temperatures are applied for the sol-gel coating layer to avoid caking of the film. the thickness of extraction phase is 30 mum, and can be increased by way of multi-coating. the extraction phase prepared by using the improved coating technology shows good thermal stability up to 300degreesc. the analyses of spiked aqueous samples containing n-alkanes or polyaromatic hydrocarbons, were carried out by using the sorptive bars and gas chromatography, which, demonstrated the applicability of the method.
