The brand new oil-in-water method D7678-11 has been published by ASTM International. Based on an infrared absorption measurement after liquid-liquid extraction with cyclohexane, this method precisely quantifies hydrocarbons on-site without using CFC or carcinogenic solvents. The ERACHECK by QuantaRed Technologies fully complies to ASTM D7678-11.
