Oil in water analysis by FTIR spectroscopy, based on ASTM D7678-11

This new ASTM method uses a more environmentally friendly non-halogenated solvent to extract and measure the oil in water in the 0.85–1000 mg/L range. The method provides the ‘total petroleum hydrocarbons’ and ‘total oil and grease’ values, with 21 times less cost per sample compared to other FTIR ASTM oil in water methods
