• long life span

• resistant to chemicals

• long term signal stability

The highly precise LAS (Laser Absorption Spectroscopy) measurement principle is based on absorption of specififi c light wavelengths by molecules to be detected. The infrared laser is tunable to 1/1, 000 wave numbers and long-term stabilized to the corresponding absorption wavelengths. The determination of the concentration follows the Lambert-Beer’s light absorption law, evaluating the relation between intensity of

transmitted (I) to incident light (I0 ) at the detector. The method is not subjected to drift and insensitive to pollution.

The measured spectrum and the model for the instrument function are compared with the HITRAN database containing the theoretical absorption spectrum of N2 O. The analysis algorithm continuously verififi es the absence of divergences and ensures a correct measurement.

If the measured spectrum ever differs from the theoretical spectrum, the system issues a warning. In this situation users can visually inspect the absorption spectrum to discover the reason fast.
