GMA3212 gas phase molecular absorption spectrometer

Brief introduction:

GMA3212 type is by using the theory of gas-phase molecular absorption spectrometry in water into a particular analysis of the second generation of products. 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.
