Determination of LV ethanol in ambient air by gas chromatography with 10% FFAP/Chromosorb W AW packed column

Determination of LV ethanol in ambient air by 10% FFAP/Chromosorb W AW packed column gas chromatography Details:

Name: Filled Column

Fixed liquid: 10% polyethylene glycol nitrobenzene modified

Support: Chromosorb W AW

Particle size: 60-80 mesh

Material: stainless steel

Specification: 2m * 4mm

Model: 10% FFAP/Chromosorb W AW

Application: GB 11524-1989 Hygienic standard for lv ethanol in the air of workplace

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a method for the determination of LV ethanol in ambient air by using distilled water to absorb samples and then directly entering a gas chromatograph, followed by FFAP packed column separation and hydrogen flame ionization detector. The method has a recovery of 94.4% to 104.2% for LV ethanol. When the sampling volume is 60L, the low detectable mass concentration of LV ethanol ZUI is 0.03mg/m3. The method is simple in pre processing, high in analytical sensitivity, and can meet the requirements of environmental analysis.
