Picarro G2307 Gas Concentration Analyzer

Atmospheric scientists, researchers, and air quality specialists need ultra-precise and stable measurements of formaldehyde gas in ambient air. In many applications, ultra-high sensitivity is also required to assure the accuracy of their measurements and the safety of their environments. And aspects like ease-of use, field deployment, and minimal maintenance of a precision instrument are highly desirable.

  • Continuous, real-time measurements in the field or lab
  • Long-term stability with guaranteed drift specification
  • Highest sensitivity, precision, and accuracy
  • Simple installation and operation

The Picarro G2307 formaldehyde gas concentration analyzer guarantees an impressive drift specification of ±1.5 parts-per-billion (ppb) over 24 hours of continuous operation, the best in its class. Additionally, the Picarro device shatters previous measurement specifications with a new world-class low-detection limit of 300 parts-per-trillion (ppt). The G2307 analyzer incorporates coated components in the critical gas pathway, resulting in a response time measurement of less than 1 minute for 90/10 Fall/Rise time challenge from 0 – 20 ppb and 20 – 0 ppb. This combination adds up to long-term stability, continuous, real-time measurement of formaldehyde gas requiring infrequent calibration and low maintenance.

In addition, the G2307 analyzer measures and corrects for H2O and CH4 concentrations, and it can report H2CO dry-basis mole fractions. The analyzer features a small footprint, rugged construction, and is relatively lightweight for easy transport from site to site, whether a lab or in the field. The analyzer can be unpacked, installed, and placed in operation within minutes. And it can operate unattended and without calibration for months.

Patented Picarro cavity ring-down spectroscopy (CRDS) technology makes the G2307 analyzer ideal for atmospheric research and monitoring of formaldehyde from automobile and aircraft exhaust, photochemical smog, and incinerator emissions. In these applications, trends are moving toward higher sensitivity measurements which are unattainable by traditional technologies, such as Fourier-Transform Infrared Spectroscopy (FTIR). The analyzer can also be used to measure sensitive trace and ambient formaldehyde for indoor air quality. Indoor sources of formaldehyde in residential and industrial structures include out-gassing from foam installation and from particleboard and plywood used in building and furniture construction.
