改进了水溶液中纳摩尔级二甲基亚砜（DMSO）的分析方法。将DMSO还原为二甲基硫醚（DMS），在吸附剂上浓缩，并通过气相色谱法进行测量。在氯化铁存在下，硼氢化钠（NaBH_4）还原DMSO的反应顺利、高效地进行，且该反应的重复性显著提高。DMSO的检测限为0.27 nM，峰面积测量的重复性为4.1%RSD（n = 5）。
An analytical method for dimethyl sulfoxide (DMSO) in aqueous samples at nanomolar levels has been improved. DMSO was reduced to dimethyl sulfide (DMS), concentrated on an adsorbent, and measured by gas chromatography. In the presence of iron chloride, the sodium borohydride (NaBH_4) reduction of DMSO proceeded smoothly and efficiently, and the repeatability of this reaction was significantly improved. The detection limit was 0.27 nM for DMSO, and its repeatability of the peak-area measurement was 4.1% as RSD ( n = 5).
