Inhalable Fraction Sampling

Ernest N. Morial New Orleans Convention Center 

The ACGIH TLV Committees have increasingly called for the use of the inhalable fraction for particulate sampling. While these calls are supported by academic evidence, there is a growing body of evidence that the limitations of the Institute of Occupational Medicine (IOM) sampler need to be considered; particularly when inertially driven particles are present. Presented in this poster are real-world results using IOM and Button Aerosol Samplers (BAS, or "button") across several industries with observations from both field and laboratory personnel. In this poster, we will review paired data sets between samplers and between O-ring materials. Through this, we will highlight limitations of these samplers including considerations for triboelectric charge and alternative approaches to results interpretation.
