Abstract
An apparatus and method to determine analytes in a fluid. One aspect of the present invention is for the determination of the oil content of water using UV, near-IR, IR or Raman spectroscopy or radiometry. In certain embodiments, a solid membrane material absorbs analytes from fluid brought into contact with it. The membrane is subsequently placed in a FTIR spectrometer, which spectrometer is enabled to determine the concentration of analytes in fluid by calibration. Certain embodiments can determine the type of hydrocarbon present, and thus can differentiate Total Petroleum Hydrocarbons (TPH) from Total Oil and Grease (TOG), without any separate sample preparation.
