1The fully automatic infrared spectrometer oil analyzer meets the standard
Automatic infrared oil analyzerMeets the national standard "HJ637-2012 Water Quality - Determination of Petroleum, Animal and Vegetable Oils - Infrared Luminescence Method"
2、Automatic infrared oil analyzerWorking structure principle
EP3000BComposed of fully automated operating software, infrared spectroscopy system, and magnetic stirring extraction system, the oil in the water is extracted using extraction solvents (CCl4 or C2Cl4) according to the extraction ratio, and the drum type three-dimensional stirring technology is used to extract the oil from the water. After removing water and impurities from the extraction solution, it is introduced into a colorimetric dish, and then analyzed and measured by the infrared oil analyzer detection system. After the measurement is completed, the instrument automatically discharges waste and cleans the pipeline.
Fully automated, without the need for operators to come into contact with carbon tetrachloride, including automatic sampling, extraction, water and impurity removal, measurement, cleaning, drainage, and data storage.
