Introduction: This instrument is suitable for the detection of total oil, petroleum or animal and vegetable oil content in various water bodies such as surface water, groundwater, industrial wastewater, domestic sewage, seawater, fishery water, farmland irrigation water, etc. The testing and testing principles are in full compliance with the current testing standards for the above-mentioned various industries or water bodies. Features: 1. Fully automatic sample measurement: realize automatic demulsification, automatic extraction, automatic water removal, automatic detection, automatic storage, etc. 2. Portable design Waterproof and shockproof: Use a special suitcase that is waterproof, shockproof, high temperature and corrosion resistant as the instrument shell, suitable for various environments such as vehicle, towing, and marine use. 3. Automatic measurement of sample volume: The instrument automatically measures the volume of the water sample in a non-contact manner. After reading the volume, the extraction agent is automatically added, and the sample is directly entered into the extraction process without sample transfer, reducing the loss of oil in the sample. 4. Three kinds of oil content are measured in one process: total oil, petroleum and animal and vegetable oils are all measured in one process, saving time and efficiency 5. Automatic switching of magnesium silicate column: the instrument automatically monitors the residual magnesium silicate, and has a spare position for magnesium silicate column. When the residual amount is insufficient, it will automatically alarm and prompt and automatically switch to the standby column. 6. The special oil-water separator filters out impurities and moisture, no need to fill with sodium sulfate water remover, and no need to replace the diaphragm 7. It can automatically judge the purity of the extractant and alarm and prompt to replace the extractant in time to avoid waste of human and material resources 8. It can flexibly set the sample volume and extraction ratio, which is suitable for the detection of samples with various levels of oil content 9. There are three methods of full-spectrum scanning sample measurement, three-wave number sample measurement, and non-dispersive single-point sample measurement to meet various testing needs 10. A variety of calibration methods: it can support three standard object calibration, standard curve calibration, and single-point calibration to ensure detection accuracy 11. Real-time printing of test results: The instrument is equipped with an embedded printer, and the measurement data can be printed in real time and viewed in real time 12. Two control methods: The instrument is equipped with a tablet installation card position. During the actual inspection, you can hold the computer or install the tablet computer on the instrument for operation. Technical parameter: Baseline stability: real-time automatic correction of zero point, no effect of baseline drift Method detection limit: 0.0125mg/L (sample 1000mL, extract 25mL, cuvette optical path 40mm) 0.05mg/L (sample 500mL, extract 50mL, cuvette optical path 40mm) Minimum detectable concentration: 0.0006mg/L The highest measured concentration: 100% oil, high concentration automatic dilution Basic measuring range: 0～100mg/L Accuracy error: ≤2% Repeatability error: RSD≤1% (30～40mg/L oil sample was measured 11 times) Linear correlation coefficient: R>0.999 Wave number range: 85000px-1～60000px-1 (2940nm～4167nm) Wavenumber accuracy: ±50px-1 Wavenumber repeatability: ±25px-1 Absorbance range: 0.00000～2.00000AU (ie transmittance 100～1%T) Scanning speed: 30 seconds/time for full spectrum scanning, 2 seconds/time for non-dispersive infrared method Sample time: ≤10 minutes Water sample volume: 0-600mL (volume automatically read) Volume reading: the instrument automatically reads, the error is less than or equal to 2%
