浩瀚色譜采用氣相色譜法測(cè)定空氣中PPm級(jí)有機(jī)硫化物。使用火焰光度(FPD)檢測(cè)器,色譜柱材料為內(nèi)徑3mm,長(zhǎng)3m玻璃柱,固定相為60—80目DMCS 201紅色載體涂漬。它能分離H_2S等七個(gè)組分。SO_2的保留時(shí)間與(CH_3)_2S很接近,但當(dāng)SO_2:(CH_3)_2S=6:1以下時(shí),SO_2不干擾(CH_3)_2S的測(cè)定。直接進(jìn)樣1ml其檢出限為:CS_2:0.5×10_(-3)μg(CH_3)_2S 1×10~(-3)μg;CH_2SH:2×10~(-3)μg(C_2H_5)_

Haohan Chromatography uses gas chromatography to determine PPm level organic sulfides in the air. Using a flame photometric (FPD) detector, the chromatographic column material is a 3mm inner diameter, 3m long glass column, and the stationary phase is 60-80 mesh DMCS 201 red carrier coating. It can separate seven components including H2S. The retention time of SO2 is very close to that of (CH3) 2S, but when SO2: (CH_3)_2S=6: When the concentration is below 1, SO2 does not interfere with the determination of (CH3) 2S. The detection limit for 1ml direct injection is: CS_2: 0.5 × 10 ^ (-3) μ g (CH3) 2S 1 × 10 ^ (-3) μ g; CH_2SH:2×10~(-3)μg(C_2H_5)_
