D18-I infrared spectrophotometer for oil measurement Introduction: The D18-I infrared spectrophotometer is mainly used for measuring the oil content in industrial wastewater, as well as for monitoring the oil content in the smoke and solid of the catering industry. This instrument is a professional instrument for measuring oil content in water bodies, gases, and solids. Features: 1. Structural design: Aluminum alloy is lightweight and has good heat dissipation performance; 2. Modulation light source: Use a low-voltage power source to reduce temperature interference and ensure instrument stability; 3. Imported light source: equipped with imported light source, low power, low voltage, greatly improving the lifespan of the light source, maintenance free; 4. Light source drive: High frequency chopping mode, eliminating benzene interference and improving performance to noise ratio; 5. Optical design: Adopting a polarizing elliptical condenser design, the light source can be observed focusing on the receiving area of the detector, which is convenient for maintenance; 6. Strictly implement the HJ637-2018 national standard, without the need for standard curve data correction, only one set of correction coefficients (X, Y, Z, F) should be applied Technical parameters: Qualitative method: infrared spectrum scanning Wavenumber position accuracy: Polypropylene film wavenumber positioning, instrument wavenumber resolution of 0.5nm Measurement basis: ρ=X • A2930+Y • A2960+Z • (A3030-A2930 ÷ F) CH accuracy: 100mg/L ± 5% (standard 8.1.1 requires not to use standard curves to measure benzene) CH2 accuracy: 20mg/L ± 5% (standard 8.1.1 requires no use of standard curve to measure n-hexadecane) CH3 accuracy: 20mg/L ± 5% (standard 8.1.1 requires no use of standard curve for measuring isooctane) Extraction solvents: carbon tetrachloride, tetrachloroethylene, trichlorotrifluoroethane, S316 Zero point stability: eliminating errors caused by drift through real-time measurement of blanks
