Abstract:
A capillary column is prepared has dimensions of 30 m × 0.53 mm and a 2.82-µm layer of poly(1-trimethylsilyl-1-propyne) (PTMSP). The loading capacity and thermal stability are studied and compared to a commercial Rt-Q-BOND column with dimensions of 30 m × 0.32 mm × 10 µm. It is shown that the loading capacity with respect to ethylbenzene is 160 ng for a column with a PTMSP layer 2.82 µm thick, which is 8 times higher than for an Rt-Q-BOND column with a layer of a poly(divinylbenzene) sorbent 10 µm thick. The separating capacity of the prepared column, calculated for certain pairs of the peaks of the components of the butene–butane fraction, is superior to that of an Rt-Q-BOND column. The macrozone of methane, the fraction of which in the mixture is more than 90%, is selectively separated from the related impurities. A comparative assessment of the repeatability of the retention times of sulfur compounds on the studied column and a commercial column shows satisfactory repeatability, and the relative mean square deviation (RMSD) does not exceed 0.47%.
