The MATRIX-MG5 features a 5 m multi-reflection gas cell and is designed for the high-precision quantification of gas compounds from very low concentrations on the ppb level up to one hundred percent. Its patented design is especially optimized for a fast gas exchange which allows for analyzing dynamic processes, like the exhausts of combustion engines. The nickel-plated gas cell and galvanic coated mirrors enable the measurement even of corrosive gases. For dedicated demanding applications, the gas cell is also available in stainless steel. Pressure and temperature sensors inside the gas cell are automatically read out and considered within the control software OPUS GA.
