G2307 Gas Concentration Analyzer

Measures H2CO, CH4, and H2O

The Picarro G2307 gas concentration analyzer provides precise, real-time measurement of formaldehyde (H2CO), methane (CH4), and water (H2O) vapor. It incorporates coated components in the critical gas pathway. This reduces the propensity of H2CO molecules to adhere to pathway surfaces, which improves measurement response time. The analyzer is an ideal solution for atmospheric research and monitoring of formaldehyde from automobile and aircraft exhaust, photochemical smog, and incinerator emissions, and it can be used to measure sensitive trace and ambient formaldehyde for indoor air quality.

  • Fast, continuous, real-time measurement of H2CO
  • 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 2 seconds, 10 seconds, and 5 minutes is 1.2, 0.6, and 0.1 parts-per-billion (ppb) for H2CO and 20, 10, and 2 ppb for CH4. H2CO rise time (10 – 90%) and fall time (90 – 10%) is less than 1 minute, 0 – 20 ppb. Drift at standard temperature and pressure (STP) over 24 hours is 1.5 ppb. Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs.
