Brief introduction: GMA3386 type is to use the principle of gas-phase molecular absorption spectrometry in water into a particular analysis of the latest generation of products. It can form a complete set of uv online digestion module, which can realize the automatic detection of total nitrogen. At present the equipment is mainly used for the determination of nitrite, nitrate, total nitrogen and sulfide, ammonia nitrogen, kjeldahl nitrogen, mercury and sulfite, the application analysis method is derived from the state environmental protection standards set by the method. Features: 1. Instrument analysis speed, a test project entire process need only 42 s; 2. Instrument analysis anti-interference ability is strong, almost without pretreatment, because the suspended solids in water, the color and the impurity ions interference; Even if didn't affect stunk black water. 3. Sample automatic drain, automatic analysis, automatic generate analysis report. 4. Online instrument equipped with heating system, analysis of nitrite and total nitrogen without the aid of cumbersome heating thermostatic waterbath, save analysis time of 20 ~ 30 minutes, greatly improve the efficiency of analysis. 5. Operation is very simple, because of the high integration of the automation technology, the use of the equipment, the operation skills for analyzing personnel do not picky, can couple as well. 6. Do not use any desiccant. Technical parameters: 1. The optical and detection system: Wavelength accuracy: 0.2 nm or less Wavelength repeatability: 0.1 nm or less; Lamp position: by computer automatic switch Warm up:, up to 4 lamps at the same time Slit: 0.1, 0.2, 0.4, 0.2 nm spectral pass band four gears is adjustable Instrument stability, more than 24 hours 2. Sample and reaction separator system: Gas-liquid separation efficiency: up to 99.99% Large diameter into here: 2.4 mm Reaction system: keep sealed state 3. The heating system: Heating method: sample delivery is heated at the same time, without also provides constant temperature water bath tank; Sensitivity: increase by about 50%.
