The Picarro G2205 gas concentration analyzer provides precise, real-time measurement of hydrogen fluoride (HF) and water (H₂O) vapor at parts-per-trillion (ppt) sensitivity with negligible drift for atmospheric science and air quality applications. It incorporates coated components in the critical gas pathway. This reduces the propensity of HF molecules to adhere to pathway surfaces, which improves measurement response time. It requires virtually no consumables, thereby offering significant ease-of-use and lower cost of ownership benefits. The analyzer is rugged and easily transportable.

• Fast, continuous, real-time measurement of HF
• Long-term stability for infrequent calibration
• Small footprint, field or lab deployable with no consumables required
• Water correction automatically reports dry gas mole fractions

Precision at 5 minutes is 30 ppt. Drift at standard temperature and pressure (STP) over 24 hours is less than ±150 ppt. Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs.
