LCS Laboratory offers sampling supplies and chemical analysis for Oil Mist by the NIOSH 5026 method (with modification). 
We had to modify the original NIOSH method to eliminate use of Carbon Tetrachloride as a solvent.
Air samples are collected on 37 mm MCE filters at 1-4L/minute using portable sampling pumps. The sampling procedure is identical to the NIOSH 0500 technique, which is shown here. LCS will provide all necessary equipment for the project.
Once the samples are collected, the laboratory extracts the oil from the cassette, removes any insoluble dust and analyzes dissolved oil using Fourier Transform Infrared Spectroscopy (FTIR). Typical detection limit is 10-20 micro gram per sample, which is more than sufficient for an industrial hygiene assessment.
