A laboratory submission sheet is finished, and the monitor is sent into the laboratory for Evaluation. The laboratory will extract the contaminant from your sorbent and utilize a diffusion coefficient to compute the focus in the gas or vapors the employee was subjected to and subsequently supply you with a composed report that contains that information and facts.
