MEASUREMENT OF REFRIGERANT EMISSIONS FROM MOBILE A/C SYSTEMS The gas portfolio of LumaSense Technologies not only helps our customers achieve process efficiency and waste reduction, but monitors the world’s most harmful and dangerous gases. Because our gas sensing solutions offer superior sensitivity over other gas detection techniques, our gas modules and instruments are particularly beneficial when the environment and human safety are involved. While there are numerous ways to detect and analyze gases, at LumaSense we utilize two different types of infrared

(IR) technologies to deliver costeffect solutions with high sensitivity, accuracy, and reliability. These are Photoacoustic (PAS) and Non-dispersive IR (NDIR) spectroscopy. As a leader in trace and multi-gas monitoring, LumaSense delivers a complete range of NDIR and PAS gas solutions for all kinds of environments and applications in the Global Energy, Industrial Materials, Advanced Technologies, as well as in many other markets and R&D applications.
The emission of man-made gases into the atmosphere has been associated with potential future adverse affects on the global climate. The automotive industry incorporates Mobile Air Conditioners and is compelled to reduce the overall emission of the frequently used coolant R134a or to introduce alternatives such as Tetrafluoropropene HFO1234yf or CO2. New methodologies for determining emission values of R134a or HFO-1234yf or CO2 based upon gas analysis using
