Fully automatic infrared oil analyzer

Fully automatic infrared oil analyzerApplication and Technical Principles:

Suitable for the determination of petroleum and animal and plant oils in industrial wastewater and domestic sewage.

After extracting the water sample with tetrachloroethylene under the condition of pH ≤ 2, determine the oil content; Adsorb the extract with magnesium silicate to remove polar substances such as animal and vegetable oils, and then determine the petroleum content. The content of oil and petroleum is calculated based on the absorbance A2930, A2960, A3030 at wave numbers 2930 cm-1 (stretching vibration of C-H bond in CH2 group), 2960 cm-1 (stretching vibration of C-H bond in CH3 group), and 3030 cm-1 (stretching vibration of C-H bond in aromatic ring), respectively, using correction coefficients. The content of animal and plant oils is the difference between the content of oil and petroleum.

●According to the national environmental protection standard "HJ 637-2018 Water Quality - Determination of Petroleum, Animal and Plant Oils - Infrared Spectrometric Method".

●Instrument qualification: The instrument has the "Type Approval Certificate for Measuring Instruments" issued by the provincial quality and technical supervision department or the market supervision and management department.

●Fully automated process: solvent addition, sample extraction, sample transfer, sample grade cleaning, oil-water separation, magnesium silicate adsorption, measurement, waste disposal, and analysis report generation are integrated into one, without the need for manual operation throughout the entire process; Fully automatic measurement of oil, petroleum, and animal and vegetable oil content.

●Number of positions for automatic sampler: 6, 8, 10, 12 (number of positions can be selected according to requirements).

●Automatic sampler system: consisting of a liquid extraction system, extraction system, cleaning system, lifting system, and 360 degree rotation system, the automatic sampler is equipped with a dedicated extraction cup. After collecting water samples, they can be directly used as extraction cups on the machine without the need for water sample transfer.

●Infinite loop sampling system: During the sample testing process, new water samples can be added in real-time to achieve infinite loop measurement of water samples, allowing the instrument to continuously measure no less than 20 samples without interruption.

●The automatic sampler is equipped with a dedicated sample cleaning position. After each sample extraction is completed, the cleaning system is activated to extract reagents and thoroughly clean all pipelines, pump valve systems, and minimize cross contamination.

●Using imported liquid level ranging sensors to measure the volume of the extraction cup water sample, written into a software workstation, there is no need to read the sample volume with the naked eye or transfer it to a measuring cylinder for reading. The volume measurement error is less than 2%.

●The measurement method has been upgraded to include both fully automatic and manual sample measurement methods. Based on measuring the concentration of oil in water, it can also be compatible with measuring cooking fumes and solid oil in the catering industry.

●Adopting a sapphire material multi-channel switching valve to replace the numerous electromagnetic valve designs currently available on the market, reducing instrument failure rates; The switching valve is equipped with a dedicated waste liquid channel to reduce cross contamination between samples.

●Adopting a precision injection pump design, it has excellent precision and corrosion resistance.

●Automatic separator system: using oil-water separation membrane for trace water removal. Using magnesium silicate adsorption column for oil-water separation and animal and vegetable oil adsorption separation, the system intelligently prompts to replace the magnesium silicate adsorption column.

●Measurement time: Fast measurement speed, measuring a sample in at least 7 minutes.

●Software Workstation: Flyscience3000 Workstation includes control software and data processing software, with modular design and simple operation. The data processing software can easily store detection data, generate detection reports, and has software copyright certificates.

●Exhaust gas collection: The entire process operates in a closed manner, and the volatile organic waste gas generated during the measurement process is discharged non-toxic after being adsorbed and filtered by activated carbon through the instrument's built-in automatic exhaust system.

●Waste liquid collection: The entire process operates in a closed manner, and harmful reagents generated during the measurement process are automatically discharged from the instrument system and collected by specialized waste liquid bottles.

●Dual reagent system: Carbon tetrachloride or tetrachloroethylene can be used as extractants.

●Communication interface and operating system: compatible with serial and USB interfaces, suitable for WIN7, 8, and 10 operating systems.

●Water sample volume: any from 0-700ml

●Solvent addition volume: 0-700ml, any

●Sample measurement range: 0-9600mg/L (automatic dilution beyond the range)

●Calibration method: The instrument can be measured using calibration coefficients or standard curves to meet different needs

●Instrument detection limit: DL ≤ 0.02mg/L (measured 11 times SD of blank solution of tetrachloroethylene)

●Repeatability: RSD ≤ 0.2% (tested 11 times for 30-40mg/L oil standard samples); RSD ≤ 3% (0.5mg/L water sample)

●Correction coefficient accuracy: Take an appropriate amount of petroleum standard solution, prepare an appropriate concentration of petroleum standard solution with tetrachloroethylene as the solvent, and perform the same steps as the sample measurement. The relative error between the measured value and the standard value is within ± 10%

●Absorption range: 0.0000-2.0000 AU (i.e. transmittance of 100-1% T)

●Wave number range: 3400cm-1 to 2400cm-1 (i.e. 2941 to 4167nm)

●Standard method and measurement time: Infrared spectrophotometry, the instrument has a full wavelength continuous infrared absorption spectrum, full spectrum scanning, 30S/time; Non dispersive infrared photometry, 1 second per measurement.
