This calculation of a sampling or uptake rate uses the diffusion coefficient of a specific chemical (D) and the cross-sectional area (A) and length (L) of the sampler's diffusion path (based on sampler geometry).
This SKC Air Sampling guide is a reference only to assist users in finding the method, sampling equipment, and sampling media for a specific compound. This publication is intended for general information only and should not be used as a substitute for reviewing applicable government regulations, equipment operating instructions, or legal standards. Users must consult the appropriate sampling method for the compound of interest before sampling. The sampling parameters shown here are suggestions based on the ranges or volume, flow, and time specified in the methods. It is the responsibility of the analyst performing the sampling and analysis steps to adjust the parameters so that the required detection limits can be obtained.
