Infrared Spectrometer Oil Content Analyzer

Principle

When a monochromatic light through the test solution, the light will be absorbed. Light be absorbed proportional to the concentration of the test solution. Conform Beer’s law:

A= log（1/T）=log（I0/I）

T Transmission

I0 Incident light intensity

I Transmitted light intensity

A Absorbance

Oil concentration:

2.3 Applied range

The instrument is mainly used in the measurement of oil content in surface water, groundwater and industrial waste water, as well as the monitoring of oil content in the flue gas of catering industry and the monitoring of oil content in solids. It is a professional instrument for measuring oil content in water, gas and solids.

It is widely used in environmental monitoring systems of various departments, testing centers and laboratories of large and medium-sized enterprises such as petrochemical industry, hydrology and water conservancy, tap water, sewage treatment plants, thermal power plants, iron and steel enterprises, scientific research and teaching in universities, agricultural environmental monitoring, railway environmental monitoring, automobile manufacturing, marine environmental monitoring, traffic environmental monitoring and environmental scientific research.
