Product details
Product Overview
The Picarro G2307 gas concentration analyzer can accurately measure formaldehyde (H2CO), methane (CH4), and water vapor (H2O) in real-time. This analyzer is equipped with coating components in key gas pathways, which reduces the tendency of H2CO molecules to adhere to the surface of the gas pathway, thereby improving the measurement response time. This analyzer is an ideal solution for atmospheric research and monitoring of formaldehyde in automobile and aircraft exhaust, photochemical smog, and incinerator emissions. It can be used to measure sensitive trace amounts of formaldehyde and environmental formaldehyde to ensure indoor air quality.
Product Features
• Fast, continuous, and real-time measurement of H2CO
• 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 correction function, automatically reporting dry gas mole fraction

Application precautions |
When the concentration of organic compounds in the sample far exceeds the normal environmental level, it may interfere with the measurement, including but not limited to ethane, acetylene, ammonia, and other nitrogen-containing and sulfur-containing compounds. Users should verify whether the experimental samples are suitable. If unsure, please contact us to discuss the specific situation of the experiment. |
