PAS technology is perfect for many different industries. From identifying toxic gases to the monitoring of organic compounds in production plants, laboratories, and hospitals.Thanks to its high resolution, the ETG QE-PAS unlocks its full potential in process control such as fermentation monitoring or pure gas production. Photoacoustic Spectroscopy (PAS) provides greater sensitivity than conventional spectroscopic techniques. ETG QE-PAS utilises a laser as a light source, eliminating interferences. Precise measurements are possible in the ppb range and even ppt, implementing algorithms to the raw signal.We know how important it is to have a tool that is easy to use, intuitive and quick to learn. ETG Risorse e Tecnologia equips its analysers with a touchscreen monitor and an intuitive interface. All you need is a finger to access all its functions. ETG QE-PAS can be accessed remotely worldwide.
