Special column for determination of toxic substances and sulfides in workplace air
Detailed information on the dedicated column for measuring sulfides in workplace air for the determination of toxic substances:
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a method for the determination of 9 sulfur-containing compounds in ambient air using an atmospheric pre concentrator GC/FPD. The results indicate that the baseline of the atmospheric pre concentration instrument GC/FPD measurement system after inerting modification is low and there is no residue of sulfides. The correlation coefficients of the linear regression equations for 9 compounds are all above 0.995. The blank spiked recovery rates for high, medium, and low concentrations are 98.6%, 105.3%, 99.1%, 103.7%, 85.7%, and 99.7%, respectively. Except for hydrogen sulfide with a relative standard deviation of 10.9%, the relative standard deviation of the other 8 sulfur-containing compounds can be controlled within 6.9%. When the injection volume is 400 mL, the detection limit of the method is between 0.10 and 1.1 ng/m3. CO2 and H2O do not interfere with the determination of actual samples. Therefore, this method can meet the requirements of current monitoring work and is more suitable for the determination of trace sulfur-containing compounds in ambient air.
