Overview

Measure HF and H2O

Product Details

The Picarro G2205 gas concentration analyzer can accurately measure hydrogen fluoride (HF) and water vapor (H) in real-time2O) ， The sensitivity is in parts per trillion (ppt), and the drift generated for atmospheric science and air quality applications can be ignored. This analyzer is equipped with coating components in key gas pathways, which reduces the tendency of HF 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 HF
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 30 ppt. The drift within 24 hours at standard temperature and pressure (STP) is less than ± 150 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.
