G2201-iIsotope analyzer
Measure CH4And CO2The δ13C
Picarro G2201-iThe isotope analyzer integrates two Picarro δ 13C carbon isotope instruments used for measuring CO2 and CH4 into one instrument. The information provided by stable isotope ratios can now be easily and conveniently obtained, and researchers can track the movement of carbon from source to sink using a single instrument. This dual-purpose analyzer makes research work simple and fast. This analyzer is compact in size, sturdy in structure, and easy to transport to the site; Researchers can use the real-time results generated by the analyzer to change the ongoing work process and obtain the best results for time limited on-site activities.
Only on-site deployable analyzers can synchronize high-precision measurement of δ 13C in CO2 and CH4
●Three measurement modes: CO2 only mode, CH4 only mode, and CO2 and CH4 combined mode
●Achieve excellent accuracy with a small fraction of IRMS operating costs - reducing calibration, minimizing maintenance, and eliminating the need for consumables
This analyzer has three operating modes: 1) CO2 only mode, 2) CH4 only mode, and 3) CO2 and CH4 combined mode. In combination mode, staggered measurements of CO2 and CH4 are taken every few seconds to generate a faster sampling rate than the gas conversion time in the chamber. When the analyzer is in CO2 only mode or CH4 only mode, the accuracy will be improved because more measurement time can be used for individual molecules. In all modes, this analyzer can accurately measure the concentrations of CO2, H2O, and CH4, and it requires less calibration than other instruments based on spectral absorption. The G2201-i analyzer can be paired with various peripheral devices to extend and expand its functionality.

| Application precautions |
The concentration measurements of H2O and CO2 will be disturbed when they significantly exceed the specified dynamic range. Similarly, certain organic compounds, ammonia, ethane, ethylene, or sulfur-containing compounds can also affect the measurement. Users should verify whether the test samples are suitable. If unsure, please contact us to discuss the specific situation of the experiment. In the application of closed-loop measurement, attention should be paid to the possibility of pressure drop in the air path causing external air to enter the system. |
