Product Description Meeting the standard: Conform to national standard"HJ637-2012 water quality the determination of petroleum and animal and plant oil Infrared photometric method" Technical principle: According to HJ637-2012 standard, with the method of magnetic stirring extraction ,using carbon tetrachloride to extract oil substances in the water, then use oil water separation membranes to replace anhydrous sodium sulfate isolating impurities and moisture, isolate oil and carbon tetrachloride solution, determine the oil content of total extract.Using department of instrument:Environment monitor system, petrochemical, hydrology and water conservancy, water supply company, sewage treatment works, thermal power plant, iron and steel enterprise, teaching and research work in university, agricultural environmental monitoring, Railway environmental monitoring, automobile making, marine environmental monitoring, transport environment monitoring, environmental scientific researches, inspection room, used in laboratory.Instrument application range:The equipment is mainly used in the measurement of oil content in the surface water, groundwater, industry waste water.Work structure principle:WOA-3000 fully automatically infrared oil analyzer is composed of host computer, operating software, infrared spectroscopic system and magnetic stirring extraction system, using extraction solvent (CCl4 or C2Cl4) in a certain proportion, extract oils in the water with the method of drum type stereo stir extraction technology, then after removing water and impurity lead the extracted solution to cuvette by filter unit. Next infrared spectroscopic system measure and analyze. If installed with specialized magnesium silicate filter device, it could measure the content of petroleum and animal and plant oil. After finishing measurement , automatically discharge waste and clean instrument pipeline. The whole process of automation, without operator contacting with carbon tetrachloride, that is automatic filling, automatic extraction, automatic water and impurity removal, automatic measurement, automatic cleaning, automatic liquid discharge and store data.Technical index:Detection limitDL<0.02mg/L (calculate 3 times standard deviation measuring 11 times blank)wave-number range3400cm-1~2400cm-1(2941nm~4167nm)Absorbency range0.0000~2.0000AU (transmittance 100~1%T)RepeatabilityRSD≤1% (20-100mg/L Oil sample determined 11 times)Measurement accuracy<±2 %Related coefficientR>0.999water sampling volume5ml--600ml or 5ml--1000ml detected sample amountContinuously test 6-10 samples Main instrument characteristics:1. Full automation: automatic sampling, extraction, dewater and filter, measurement, drainage, cleaning, and can continuously do 6-10 water samples.2. Healthy and safety: Don't need the operator to participate in the extraction, without contacting with carbon tetrachloride, to ensure the healthy and safety of the operator.3. With high extraction efficiency, with high efficiency and stable drum type magnetic stirring extraction technology, extraction rate is more than 95%.4. With the core technology: equipped with imported oil/water separation membrane to filter, instead of anhydrous sodium sulfate, one membrane can be used for one hundred times.5. Can upgrade to use reagents, such as tetrachloroethylene proceeding in full automatic extraction and detection , instead of great toxicity of carbon tetrachloride solution.6. The extracting method is accord with national standard HJ637-2012, the extraction result is consistent with GB Code Method.7. Adding magnesium silicate adsorption column can be upgraded to measure the mineral oil and animal and plant oil, adding sampling apparatus can be upgraded to online monitor.8. True three wave number, clear infrared three wave spectrum diagram, accuracy scale, could clearly display absorb spectrum diagram and absorbance produced by three wave numbers.9. One key calibration: wavelength positioning, blank and standard oil sample automatically detect and correct.10.One key accomplishment: Adjust blank and multiple water sample to detect can be completed by one key, convenient to operate.11. Spare parts quality assurance: imported accessories such as electromagnetic valve pump accessories, to ensure that the instruments are durable, effectively reducing the failure rate;12. The whole system adopts anti-acid and alkali, anti- carbon tetrachloride, completely anticorrosive and non-oleophylic material, run cleaning process, reducing the cross contamination.13. Automatic dilution and enrichment: dilute and concentration ratio can be set arbitrarily.14. Using Windows 7 and Windows 8 operating system control.15. Adopt the most stable and mature. NET4.0 platform green free installed oil analyzer software.16. External desktop computer host, convenient operation, simple structure, convenient maintenance.
