Overview

G2308 gas concentration analyzer measures N2O, CH4, and H2O

Product Details

The Picarro G2308 gas concentration analyzer can accurately measure nitrous oxide (N2O), methane (CH4) with a sensitivity of parts per billion (ppb), and water vapor (H2O) with a sensitivity of parts per million (ppm) simultaneously. The drift generated for atmospheric science, air quality, and quantitative emission applications can be ignored. This analyzer can operate in open or closed systems and can be easily integrated with chamber systems.

Synchronous continuous measurement of N2O and CH4
Billion parts per billion (ppb) sensitivity, accuracy, and precision
Can operate in open or closed systems and easily integrate with chamber systems
Equipped with water vapor correction function, automatically reporting dry gas mole fraction

For N2O, the accuracies at 1 minute and 5 minutes are<10 ppb='' and=''>10><3.5 ppb, and for CH4=''>3.5><7 ppb='' and=''>7><3>3>

Analyzer specificity: Picarro cavity ring down spectroscopy (CRDS) technology uses an extremely narrow spectral region. Compared with other spectroscopic measurement techniques, this greatly reduces the possibility of interference from other gas components. But in actual samples, interference sometimes occurs. The Picarro analyzer is equipped with interference detection software and has been tested and characterized for its susceptibility to the following components:
