G2108 gas concentration analyzer measures HCl

The Picarro G2108 gas concentration analyzer can accurately measure hydrogen chloride (HCl) and water vapor (H2O) in real-time, with a sensitivity of parts per trillion (ppt), and the drift generated for atmospheric science and air quality applications can be ignored. This analyzer reduces the tendency of HCl molecules to adhere to the surface of the gas pathway, thereby improving the measurement response time. This analyzer requires almost no consumables, therefore it has significant advantages of ease of use and lower purchase cost. This analyzer has a sturdy structure and is easy to transport.

• Fast, continuous, and real-time measurement of HCl

• Long term stability to meet low-frequency calibration requirements

• Small footprint, suitable for on-site or laboratory deployment, no need for consumables

• Equipped with water vapor correction function, automatically reporting dry gas mole fraction

The accuracy at 5 minutes is less than 120 ppt. The drift within 24 hours at standard temperature and pressure (STP) is ± 400 ppt. The moisture correction software will automatically report the dry gas mole fraction to help reduce the complexity of research work and save consumable costs.
