haohan恶臭空气中有机硫化物的测定HH一sulfide-III专用柱赛默飞3m*3mm

GB/T 14678-1993 《空气质量 硫化氢、甲硫醇、甲硫醚和二甲二硫的测定 气相色谱法》 中关于 填充柱 的部分。

这个标准是中国的国家标准，用于测定环境空气或恶臭污染源排放中的四种含硫化合物。虽然该标准年代较早，且现代实验室更多使用灵敏度和分辨率更高的毛细管柱，但了解填充柱的配置对于理解方法原理和应对特定情况（如高浓度样品）仍有其价值。

浩瀚色谱（山东）应用技术开发有限公司，采用HH一sulfide-III硫专用柱气相色谱法测定空气中PPm级有机硫化物。使用火焰光度(FPD)检测器,色谱柱材料为内径3mm,长3m四氟柱,它能分离H_2S等七个组分。SO_2的保留时间与(CH_3)_2S很接近,但当SO_2:(CH_3)_2S=6:1以下时,SO_2不干扰(CH_3)_2S的测定。直接进样1ml其检出限为:CS_2:0.5×10_(-3)μg(CH_3)_2S 1×10~(-3)μg;CH_2SH:2×10~(-3)μg(C_2H_5)_

The section on packed columns in GB/T 14678-1993 "Air Quality - Determination of Hydrogen Sulfide, Methyl Mercaptan, Methyl Sulfide, and Dimethyl Disulfide - Gas Chromatography Method".
This standard is a national standard in China, used to determine four sulfur-containing compounds in ambient air or odor pollution source emissions. Although this standard is older and modern laboratories use capillary columns with higher sensitivity and resolution, understanding the configuration of packed columns is still valuable for understanding method principles and responding to specific situations (such as high concentration samples).
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses HH sulfide III sulfur specific column 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 and 3m long PTFE column, which can separate seven components including H2S. The retention time of SO2 is very close to that of (CH3) 2S, but when SO2: (CH3) 2S=6:1 or less, 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)_
