The service life of organic vapor cartridges was determined for ten vapors at concentrations between 50 and 3000 ppm. The breakthrough time (tb) conformed to the empirical expression tb = aCf, where C is the concentration in ppm and a and be are constants. The average value for b at 10% breakthrough was -0.67 +/- 0.17. The service life is inversely proportional to flow rate for acetone and benzene.
测定了10种蒸汽在50至3000 ppm浓度下有机蒸汽滤筒的使用寿命。穿透时间(tb)符合经验表达式tb = aCf,其中C是以ppm为单位的浓度,a和b为常数。10%穿透率时b的平均值为-0.67±0.17。丙酮和苯的使用寿命与流速成反比。
