ABSTRACT:
An apparatus and method of determining trace levels of materials, such as oil and grease, which are present in liquids, such as water. The device and method allow the material to be extracted from the liquid by filtration, the material to be removed from the filter by a low boiling point solvent, and excess water to be removed from the solvent, by a single device. The apparatus is characterized by a tube having a manifold extending from the tube, with a valve which directs entry into the tubes which comprise the manifold. A crossover tube and an inner tube direct vacuum to allow a single vacuum connection to pull the liquid, and subsequently the solvent, through the apparatus. A drying cartridge is attached to a tube of the manifold to eliminate excess liquid from the solvent during the normal operation of the device.
