Footnotes
For sampling in Chromium plating operations, PVC filters (225-802) require special treatment after receipt at the laboratory. Alternatively quartz fiber filters (225-1827) treated with NaOH may be used. Refer to the method for details.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.
