Airborne Oil Mist

Oil Mist Analysis is performed by Fourier Transform Infrared Spectrometry (FTIR), Method Niosh 5026

Sampling for Oil Mists can be performed with 5.0 micron Polyvynil chloride (PVC) or 0.8 to .45 micron Mixed Cellulose Ester (MCE) filters.  Personal monitoring is typically performed at slightly higher flow rates for a longer duration.  Care should be taken to avoid filter clogging which  will alter the flow rate and total volume.  If the flow rate drops indicating an overloaded filter, terminate the sampling.  If possible, submit a vial of the oil in question for standard preparation.
