However, the highest flow rate will be dependent on the type of sorbent used, the sampling environment, anticipated concentrations, and any possible interferences. See the selected sampling method for information on the maximum flow rate and breakthrough volumes. Sampler capacity is a conservative estimate of the total mass of chemical that can be absorbed on the sampling media, without loss or overloading. Use the sampling method to determine the working range in ppm and ug per sample. This will give you an approximate range for capacity.
Blanks are an important quality control component of any air sampling program.
Blanks ensure that the background of the sampling media is below acceptable limits. Blanks also verify that the analytical procedure is functioning within acceptable parameters. Blanks are not required for the analysis of Assay Technology badges. Each lot must meet background acceptance criteria before shipment of the product. Please refer to Assay Technology's Industrial Hygiene Sampling Guide for a complete listing of chemicals, and appropriate sampling media.
