用新型WY扩散型有机溶剂个体采样器对甲苯等15种蒸气进行实验,结果表明,在一定浓度下暴露不同时间,则气相色谱上峰值与内标峰值之比与暴露时间呈高度直线相关;甲苯等四种蒸气在不同浓度下暴露一定时间,则峰值比与暴露浓度呈高度直线相关。根据实验结果,求出15种蒸气的换算系数。根据它和暴露时间与峰值比能算出暴露浓度。
Fifteen kinds of vapors, such as toluene, were tested with a new WY diffusion-type organic solvent sampler. The results showed that there was a highly linear correlation between peak and internal standard peak times and the exposure time under a certain concentration of exposure time. Toluene When the four kinds of steam were exposed at different concentrations for a certain period of time, the peak ratio was highly linear with the exposure concentration. Based on the experimental results, the conversion factors of 15 kinds of vapors were obtained. According to it and the exposure time to peak ratio can calculate the exposure concentration.
