浩瀚色譜（山東）應用技術開發有限公司采用"吸附管采樣—熱脫附—氣相色譜-質譜法"同時測定環境空氣中甲硫醇,乙硫醇,甲硫醚,乙硫醚和二甲基二硫醚5種有機硫化物,以全掃描模式定性,選擇離子掃描法定量.考察了吸附管類型,采樣流量,樣品保存方式等因素對樣品回收率的影響.實驗結果表明:在吸附管類型為多孔聚合物吸附劑(Tenax TA)及硫分子篩吸附劑(Sulficarb)二合一填料,采樣流量為400 mL/min,樣品冷藏保存的條件下,5種有機硫化物的質量濃度分別在5.35×10^(-3)~8.56×10^(-2),6.93×10^(-3)~1.11×10^(-1),6.93×10^(-3)~1.11×10^(-1),1.01×10^(-2)~1.61×10^(-1),1.01×10^(-2)~1.68×10^(-1) mg/m^(3)的范圍內與峰面積呈良好的線性關系;當采樣體積為10 L時,方法檢出限為1.13×10^(-3)~2.80×10^(-3) mg/m^(3),相對標準偏差為2.76%~7.73%,加標回收率為78.5%~106.0%.對實際樣品的測定結果與GB/T 14678—1993方法無顯著性差異.

Special column for determination of 5 kinds of organic sulfur compounds in ambient air
Special column for determination of 5 kinds of organic sulfides in ambient air for sulfur Details:

Name: Special column for sulfide

Stationary Phase: Dedicated

Specifications: 3m*3mm

Model: HH-sulfide-III

Application: Determination of 9 kinds of sulfides such as hydrogen sulfide, carbonyl sulfide, carbon disulfide, thiophene, methyl sulfide, methyl mercaptan, ethyl mercaptan, ethyl sulfide, dimethyl disulfide, etc.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts "adsorption tube sampling-thermal desorption-gas chromatography-mass spectrometry" for simultaneous determination of methyl mercaptan, ethyl mercaptan, methyl sulfide, ethyl sulfide and dimethyl sulfide in ambient air Five organic sulfides of disulfide were qualitatively characterized by full scan mode and quantified by selected ion scanning method. The effects of adsorption tube type, sampling flow rate, and sample storage method on sample recovery were investigated. The experimental results showed that: It is a two-in-one packing of porous polymer adsorbent (Tenax TA) and sulfur molecular sieve adsorbent (Sulficarb), and the sampling flow is 400 mL/min. 10^(-3)~8.56×10^(-2),6.93×10^(-3)~1.11×10^(-1),6.93×10^(-3)~1.11×10^(-1 ),1.01×10^(-2)~1.61×10^(-1),1.01×10^(-2)~1.68×10^(-1) mg/m^(3) range and peak area When the sampling volume was 10 L, the detection limit of the method was 1.13×10^(-3)~2.80×10^(-3) mg/m^(3), and the relative standard deviation was 2.76% ~7.73%, and the recovery rate of standard addition was 78.5%~106.0%. There was no significant difference between the measurement results of the actual samples and the GB/T 14678-1993 method.
