Revolution in Oil in Water Measurement: Withdrawn ASTM D3921 gets replaced by CFC-free ASTM D7678

Post questions, thoughts or simply whether you like the content. Anton Paar has launched a new intrinsically safe portable density meter solely designed for the petroleum industry — a must-have if samples are flammable o Similarly, this test method defines petroleum hydrocarbons in water and waste water as that oil and grease which is not adsorbed by silica gel in the test method and that is measured by infrared absorption.
