此采样器,可采集空气中六种有机蒸气,它无采样泵。体积小,重量轻,既可采集个体在接触时间内的累积量也可采集定点样品。采样后取出采样介质,加二硫化碳解吸,用气相色谱法测定。对准确度、精密度、吸附容量、样品储存期、风速影响、湿度影响及干扰等进行了实验观察。六种蒸气全过程的准确度为±7.7～±13.6%,符合NIOSH的推荐标准。合并变异系数为 2.7～5.3%。文中还报告了现场测定结果。
This sampler, can collect six kinds of organic vapor in the air, it has no sampling pump. Small size, light weight, can collect the cumulative amount of contact time in the individual can also collect fixed-point samples. After sampling, remove the sample medium, add carbon disulfide desorption, determined by gas chromatography. The experimental observations were made on the accuracy, precision, adsorption capacity, sample storage period, wind speed, humidity and interference. The accuracy of the six steam throughout the process of ± 7.7 ~ ± 13.6%, in line with NIOSH recommended standards. The combined coefficient of variation is 2.7 ~ 5.3%. The article also reported on-site measurement results.
