Mid infrared TDLAS nitrous oxide (N2O) ppm concentration analysis system 4.56um

TDLAS (Tunable Diode Laser Absorption Spectroscopy) is a new gas detection method developed by combining a diode laser with a long path absorption cell, which uses laser wavelength modulation to pass through the characteristic absorption region of the measured gas. The spectrum of the semiconductor laser source used in TDLAS technology has a width much smaller than the broadening of gas absorption lines, resulting in a single line absorption spectrum. Therefore, TDLAS technology is a high-resolution absorption spectroscopy technique. Nitrous oxide, also known as laughing gas, is an inorganic substance with the chemical formula N2O. It is a hazardous chemical that is colorless and sweet smelling. It is an oxidant that can support combustion under certain conditions, but is stable at room temperature. It has a slight anesthetic effect and can make people laugh. Laughing gas entering the bloodstream can cause hypoxia in the body, and long-term consumption may lead to high blood pressure, fainting, and even heart attacks.
