    Abstract

    Samples of straight, soluble, semi-synthetic, and synthetic metalworking fluids (MWF) were spiked onto polytetrafluoroethylene (PTFE) membrane filters, stored overnight, and analyzed using a provisional American Society for Testing and Materials (ASTM) method for metalworking fluids. That technique involves collection of aerosolized fluid on PTFE membrane filters and separation of the fluid from co-sampled particulate matter via extraction of the filter with a blend of dichloromethane: methanol:toluene. The extraction of all fluids from the filters was quantitative over the range 200 to 815 µg for the straight fluid, from 223 to 878 µg for the soluble fluid, from 51 to 189 µg for the semisynthetic fluid, and from 102 to 420 µg for the synthetic fluid. For those weights of all four fluids spiked at levels ⩾200 µg, the precision (%relative standard deviation or %RSD) was estimated to be 4% for the total weight procedure and 5% for the extraction procedure. Limits of quantitation, estimated from blanks carried through the entire analytical procedure, were 30 µg for the weighing technique and 60 µg for the extraction technique.
