Portable Infrared Spectroscopy Oil Content Detector

KN-EP600 Infrared Spectroscopy Oil Detector 

Overview 

  KN-EP600 Infrared Spectroscopy Oil Detector will extract oil substances in water with tetrachloroethylene, determine the total extract, then adsorb the extract with magnesium silicate, and determine oil after removing polar substances such as animal and vegetable oils. The contents of total extracts and petroleum are calculated by absorbance a2930, a2960 and a3030 at bands with wave numbers of 2930cm^-1 (stretching vibration of C-H bond in CH2 group), 2960cm^-1 (stretching vibration of C-H bond in CH3 group) and 3030cm^-1 (stretching vibration of C-H bond in aromatic hydrocarbon) respectively. The content of animal and vegetable oil is calculated according to the difference between the total extract and petroleum content 

The use of the instrument sector 

  Environmental monitoring system, petrochemical, hydrology and water conservancy, water companies, sewage treatment plants, thermal power plants, iron and steel enterprises, universities and colleges research and teaching, agricultural environmental monitoring, railway environmental monitoring, automobile manufacturing, marine environmental monitoring, traffic environmental monitoring, environmental research and other testing rooms, laboratories use. 

Application scope of the instrument 

  The instrument is mainly used in the measurement of oil content in surface water, groundwater, industrial wastewater, and also can be used for the monitoring of oil in the flue gas of the catering industry and the monitoring of oil content in solids. This instrument is a professional instrument for measuring the oil content in water, gas and solid.
