LCS Laboratory offers sampling media and the chemical analysis for Oil Mist using the NIOSH 5524 method. The method was originally developed and still used for the analysis of Metal Working Fluids.
Samples are collected on 37 mm PTFE filters or 25 mm IOM samplers. During analysis, mineral oil is selectively extracted from the filter and separated from the dust. Oil is weighed by the laboratory and reported with a sensitivity of 100 μg/sample.
In addition, the sample can be analyzed for Total Dust. This small additional test gives you a measure of metal dust on the sample, which is the difference between the dust weight and oil weight.
The method can be modified and used to collect Inhalable , Respirable, Thoracic, or Total fractions of Oil mist and dust.
