    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.
