Rapid measuring instrumentProvide to the United StatesWILKScompanyInfraCal CVHOil analyzer in water (infrared oil analyzer)/Total Petroleum Hydrocarbon Analyzer, NationalWILKScompanyInfraCal CVHOil content analyzer in waterDomestic first level agent sales.

the United StatesWilksThe company is the world's leading supplier of infrared equipment and has strong technical accumulation in the field of infrared spectroscopy.WilkscompanyInfraCalSeries of water oil analyzer, includingHATR-T2，CVHandCHThree models are already considered for measurementTOG/TPHThe standard instruments for total oil content and total petroleum hydrocarbon content have been adopted by many laboratories in the petrochemical industry both domestically and internationally.

InfraCal CVHThe water oil analyzer adoptsEPAmethod413.2and418.1Xiang orASTMStandard testing methodD7066-04The corresponding extraction solvents are Freon and tetrachloroethylene,S-316，AK-225Or other infrared transmission solvents can be used for extraction, which are characterized by being heavier than water. After extraction, the solvent sinks to the bottom of the water and is then extracted using relevant methods. Due to the absence of evaporation during the analysis processCVHHas higher measurement accuracy. The analyzer is equipped with a built-in groove, which does not require the entire analysis10Minutes, the highest instrument accuracy can be achieved2 ppm.

InfraCal CVHPrinciple of Oil Content Analyzer in Water

InfracaltypeTOG/TPHInfrared analyzer is based on the rapid determination of total oil and fat in water and soil samples（TOG）And total petroleum hydrocarbons（TPH）The infrared spectroscopy method for concentration works in accordance with the Lambert principle-Bill's Law. Using a beam of intensityI0The sample is irradiated with characteristic infrared light, and due to the absorption of characteristic infrared light by the oil, the transmitted light intensity will be weakenedIThe absorbance of the sample for characteristic infrared light isA=lg I0/IAccording to the Lambertian absorption of light-Bill's law, absorbance and oil concentration in the sample（C）The relationship isA=abCAmong themaFor the absorption coefficient,bThe thickness of the sample pool is proportional to the absorbance of the sample and the concentration of the oil. Usually, the manufacturer has established a calibration system using a set of samples with known solubility when leaving the factory. Users can obtain the relationship between absorbance and oil concentration. Based on this relationship and the absorbance of the tested sample, the oil concentration in the tested sample can be calculated.
