GMA3376
GMA3376 Gas-phase Molecular Absorption Spectrograph (GMA3376 GMAS)
GMA3376 is the third-generation GMAS using high-performance hollow cathode lamp as light source. It is upgraded and modified on the technology platform of GMA3212 to meet the higher requirement of measuring process. The development of this product results from years of experience of Beiyu Instruments in GMAS R&D and manufacturing practice.
Retaining GMA3212’s features of stability, reliability and accuracy, GMA3376 is applied to measure ammoniacal nitrogen, nitrite nitrogen, nitrate nitrogen, Kjeldahl nitrogen, nitride, sulfide and sulfur dioxide etc. in water samples.
Features
1. GMA3376 uses hollow cathode lamp as light source. With the automatic lamp holder, it can automatically change and accurately adjust the position of cathode lamps when the tested wavelength is switched.
2. The samples usually do not need to be pretreated, as the samples’ chromaticity and turbidity don’t influence the analysis when using GMA3376 to conduct measuring process
3. The process is extremely fast at no more than one minute for every single sample testing.
4. The operation is very simple under the automatic control by computer.
5. No harmful or toxic reagent is applied in the analysis.
6. Testing results are accurate and reliable with the recovery rate of the re-added water sample is between 95%～105%, and the RSD(relative standard deviation) of repetitive measurement（n=6，A>0.050）is ≤1%.
7. The measurable concentration scope is broad from 0.001ppm to 1000ppm.
