AJ-3700 Gas Phase Molecular Absorption Spectrometer
Introduction: AJ-3700 gas phase molecular absorption spectrometer is used for the determination of nitrides and sulfides in surface water, groundwater, seawater, drinking water, domestic sewage and industrial sewage. Features: 1. Light source system: determine the light source used for the absorption of characteristic spectrum; 2. Structural design: Modular design of functional components and clear division of functional areas; 3. Single-point calibration function: only need to prepare the standard solution with the highest concentration 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. Pressure monitoring function: adopt mechanical + electronic dual pressure monitoring system to ensure user safety; 6. Homogeneous purge system: stabilized air source + constant flow valve, flow control is more accurate, reliability is better, and the time and process of purge homogenization can be defined; 7. On-line water removal system: semiconductor automatic water removal, PWM temperature feedback control, optimize water removal efficiency; 8. Measurement method: continuous sampling; 9. 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: 0.0005Abs (30min); The linear coefficient of the standard curve: r>0.9998.
