The infrared oil tester is a special infrared spectroscopy analysis instrument for the determination of oil content in surface water, groundwater, industrial wastewater, soil, waste gas from fixed pollution sources, oil smoke and oil mist. The measurement accuracy is high, and a high-precision 24-bit AD detection chip is used for analog-to-digital conversion, which can accurately measure the UV-level small signal.
The measurement steps of the infrared oil tester are recommended by the instrument
1.Collect water samples: Select a representative water sample, collect it in a clean glass or polyethylene plastic bottle, and measure it as soon as possible.
2.Sample pretreatment: The collected water samples are filtered with fiberglass paper to remove suspended solids and impurities. For turbid water samples, centrifugation or static precipitation is required.
3.Extraction: The pretreated sample is extracted with an organic solvent to separate petroleum or animal and vegetable oils.
4.Concentration: The extract is concentrated for subsequent determination.
5.Determination: Determination is carried out using an infrared spectrophotometer or ultraviolet spectrophotometer to calculate the content of petroleum or animal and vegetable oils according to the standard curve.
6.Result analysis: According to the measurement results, the pollution status of the water body is analyzed, and the corresponding treatment measures are proposed.
