Two devices have been developed to determine the thickness of petroleum films on water. Both techniques use oil collectors which quantitatively remove the oil layer from a known surface area. The devices are weighed before and after being placed on the oil-covered water, and a small correction factor for entrained water is applied to the calculation of oil layer thickness. Reticulated, polyurethane foam discs are mounted in an open-ended cylinder to form a floating oleophilic sponge. When placed on the water, oil is absorbed within the confined cylindrical area. The second collector, a hydrophilic Teflon sheet, removes thin layers of oil from water upon contact. Because of its chemically inert character, the hydrophilic Teflon collector is useful for sampling spills for chemical identification and analysis. (Modified author abstract)
