AJ-3610 Gas Phase Molecular Absorption Spectrometer Introduction: The AJ-3610 Gas Phase Molecular Absorption Spectrometer is suitable for water quality analysis in ecological environment monitoring, hydrology and water resources monitoring, urban drainage monitoring, petrochemical environmental monitoring, and third-party testing. It can measure indicators such as nitrite nitrogen, ammonia nitrogen, nitrate nitrogen, Kjeldahl nitrogen, total nitrogen, and sulfide in water. Features: 1. The host is designed as an integrated system, incorporating online total nitrogen digestion and online ammonia nitrogen oxidation functional modules; 2. Strong anti-interference capability, allowing direct sample injection and measurement for samples with certain color and turbidity without the need for pretreatment; 3. Featuring built-in single-point calibration, automatic dilution, and out-of-limit cleaning functions, it reduces workload and operational complexity; 4. Standardized report design, with the ability to be customized according to specific requirements; 5. Powerful software editing functions allow for real-time operations such as sample addition, deletion, and emergency insertion. Technical Specifications: Wavelength detection range: 190~900nm Wavelength accuracy: ±0.2nm Wavelength repeatability: 0.1 nm Spectral Bandwidth: 0.1nm, 0.2nm, 0.4nm, 1.0nm (multiple options available) Light Source System: Automatic four-lamp rotation and switching design, capable of simultaneously installing multi-element hollow cathode lamps Optical Path Design: Straight-type external optical path Detector: Photomultiplier tube detector Baseline noise: ±0.0002 Abs Baseline drift: 0.0005 Abs (after 30 minutes of warm-up) Standard curve linearity: r > 0.9998 Measurement repeatability: ≤3% Detection limits: Nitrite nitrogen ≤ 0.003 mg/L Nitrate nitrogen ≤ 0.006 mg/L Ammonia nitrogen ≤ 0.020 mg/L Total nitrogen ≤ 0.050 mg/L Sulfide ≤ 0.005 mg/L Measurement time: 1-5 minutes per sample (depending on the test item) Anti-interference capability: Direct measurement of samples with color and turbidity is possible without pretreatment Sample bit depth: ≥40 bits Injection method: Continuous injection Reaction System: Integrated Online Total Nitrogen Digestion and Ammonia Nitrogen Oxidation Functional Modules Needle Washing System: Flow-type needle washing tank to prevent cross-contamination Power supply requirements: AC 220V±10%, 50Hz±1Hz Power: Approximately 240W Working environment temperature: 10~35°C Working environment humidity: ≤85% (no condensation) Dimensions: Approximately 390 mm in length × 360 mm in width × 720 mm in height (including the bracket) Weight: Approximately 15kg
