“…This polymer is a popular choice of sorbent, owing to its ability to retain apolar and, to an acceptable extent, also polar organic analytes, as well as its thermal stability and the fact that only a limited number of well-characterised PDMS decomposition products are formed during thermal desorption of the trapped volatiles. The first use of PDMS as an absorbent in open tubular traps (OTTs) for the analysis of VOCs was reported by Burger and Munro [1], who utilised a thick lining of PDMS in a capillary column to trap organic compounds from a gaseous sample. Solid-phase microextraction (SPME), developed by Arthur and Pawliszyn [2], is a static sorptive sampling technique in which a thin fibre coated with PDMS is used.…”

The sample enrichment probe (SEP) has recently been introduced as a user-friendly and cost-effective method for the sorptive extraction of volatile organic analytes from gaseous and aqueous samples for GC and GC-MS analyses. In a further development of the SEP technique, thinner polydimethylsiloxane (PDMS) tubing on polyimide-coated fused silica, instead of stainless steel rods or stalks, were used to produce the second-generation SEPs. The new SEP does not require widening of the needle-guiding orifice of the septum cap and analytes are desorbed at a faster rate from the thinner sleeve, which reduces the risk of carry-over. The flowless period that was previously recommended for analyses of highly volatile analytes is made redundant by the faster desorption from the thinner sorptive medium. It was found that differences in the thermal histories of SEPs are not the cause of the high relative standard deviations (RSDs) reported in our first paper on the technique. Excellent reproducibility can be attained by careful handling and storing of loaded SEPs and by rigorously following a standardised analytical protocol.

“…In recent years a few papers on the use of pieces of open tubular GC columns for isolation and enrichment of selected analytes from gaseous matrices [4,5,[8][9][10][11][12][13][14][15][16][17] and water [18][19][20][21][22][23][24][25] have been published. Open tubular GC columns have the structural features of a cylindrical denuder.…”
