浩瀚色谱（山东）应用技术开发有限公司采用"吸附管采样—热脱附—气相色谱-质谱法"同时测定环境空气中甲硫醇,乙硫醇,甲硫醚,乙硫醚和二甲基二硫醚5种有机硫化物,以全扫描模式定性,选择离子扫描法定量.考察了吸附管类型,采样流量,样品保存方式等因素对样品回收率的影响.实验结果表明:在吸附管类型为多孔聚合物吸附剂(Tenax TA)及硫分子筛吸附剂(Sulficarb)二合一填料,采样流量为400 mL/min,样品冷藏保存的条件下,5种有机硫化物的质量浓度分别在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)的范围内与峰面积呈良好的线性关系;当采样体积为10 L时,方法检出限为1.13×10^(-3)~2.80×10^(-3) mg/m^(3),相对标准偏差为2.76%~7.73%,加标回收率为78.5%~106.0%.对实际样品的测定结果与GB/T 14678—1993方法无显著性差异.

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.
