Trace NOx Isotope Gas Spectrometer


Recent years, more and more scientific researches prove that NO molecules have great meanings in air pollution, natural nitrogen cycle, geophysical and other research fields. Meanwhile, NO, as a super-star molecule in the healthy field, it also has great values in CCVd, neuroimmunology, respiratory regulation and other medical research fields.

On the basis of introducing Princeton newest laser spectrum technology patent, Healthy Photon independently developed units and methods to analyze gas nitrogen oxides and the concentration of liquid Nitroso Nitro samples. The analysis is real-time, rapid, and it has high sensitivity and no specific requirements for gas flow rate and volume. Compared to the common chemical fluorescence method and electrochemical analysis method, spectral analysis technologies have special ability to analyze the isotope, it can be widely used in environment monitor, address study, biochemical diagnosis, healthy care and other NOx and its isotope quantitative analysis field.
