AJ-3000 Gas Phase Molecular Absorption Spectrometer
Introduction: AJ-3000 gas phase molecular absorption spectrometer is used for the determination of nitrogen and sulfide in surface water, groundwater, seawater, drinking water, domestic sewage and industrial sewage. Features: 1. Light source system: measure the light source used for characteristic spectral absorption; 2. Structural design: integrated design; 3. Single-point calibration function: only need to configure the highest point concentration standard solution of the standard curve, and automatically complete the marking line drawing through automatic dilution; 4. Automatic dilution function: the sample can be automatically diluted if it exceeds the standard, and the maximum dilution factor is 40 times; 5. Homogeneous purge system: the whole measurement process is homogenized simultaneously, which effectively improves the measurement accuracy of precipitated and turbid samples; 6. On-line water removal system: semiconductor automatically removes water without using desiccant; 7. Measurement method: quantitative injection; 8. Use built-in sand core gas-liquid separation technology to improve the gas-liquid separation efficiency and measurement sensitivity by 300%. technical parameter: Wavelength detection range: 190~900nm; Wavelength accuracy: ±0.2nm; Wavelength repeatability: 0.1nm; Baseline noise: ±0.0002Abs; Baseline drift: 0.0010Abs (30min); The linear coefficient of the standard curve: r>0.9995.
