Problems solved by technology

However, most of the above methods have disadvantages such as large error in measurement results and poor stability. In recent years, some infrared spectroscopic oil measuring instruments have been circulated on the market, but many instruments use non-disperse red measurement during the measurement process, and cannot measure aromatics such as toluene at all; Moreover, there are disadvantages such as poor repeatability, undetectable low-concentration water samples, low efficiency, and low sensitivity.

Description

technical field [0001] The invention relates to a fully automatic infrared oil measuring instrument. Background technique [0002] Oil is one of the national environmental protection decisions to implement total pollutant discharge control projects. Among the eight water quality pollutants, oil is discharged after CODcr. The determination methods of oil substances have not been unified for a long time and various methods are not comparable. [0003] The methods used in the past mainly include: gravimetric method, pycnometer method, turbidimetric (solvent change) method, turbidimetric (ultrasonic) method, gas chromatography, resistance pyrolysis method, ultraviolet spectrophotometry (225nm, 254nm), Fluorescence method, non-dispersive infrared method, three-wavenumber infrared spectrophotometry. However, most of the above methods have disadvantages such as large error in measurement results and poor stability. In recent years, some infrared spectroscopic oil measuring instru...
