Evaluation of the use of an SKC button inhalable aerosol sampler with a Grimm aerosol monitor to determine air concentrations of subtilisin

The results of the statistical evaluation from the aerosol monitoring results in the enclosure indicate the Button inhalable sampler compared with the results from the Grimm aerosol monitor may be a valid method for determining airborne subtilisin concentrations for aerosols with diameters less than or equal to the 25 μm particle size. However, due to all results below the limit of quantitation at the DCS production area, it is concluded that there are insufficient results to determine if the Button sampler with the Grimm aerosol monitor can be used in the workplace.
