This project was undertaken to study the effect of dry airflow rate and bed weight on organic vapor respirator cartridge breakthrough curves for a single vapor (acetone) and challenge concentration (1060 ppm average). Dried cartridges from a single manufactured lot were used. The data were analyzed using three applications of the Wheeler equation, including (1) varying bed weight, (2) varying residence time, and (3) fitting the breakthrough curve. These approaches are discussed and equations given. Values for the adsorption capacity (We) and the rate coefficient (kv) are presented and compared. Based on these comparisons, limitations of the Wheeler equation are discussed and guidelines given concerning its use.
本项目旨在研究干燥气流速率和床层重量对单一蒸汽（丙酮）及挑战浓度（平均1060 ppm）下有机蒸汽呼吸器滤毒罐穿透曲线的影响。使用了来自同一生产批次的干燥滤毒罐。数据采用惠勒方程的三种应用进行分析，包括（1）改变床层重量，（2）改变停留时间，以及（3）拟合穿透曲线。讨论了这些方法并给出了方程。给出并比较了吸附容量（We）和速率系数（kv）的值。基于这些比较，讨论了惠勒方程的局限性并给出了关于其使用的指导原则。
