Picarro-G2207-i Isotope and Gas Concentration Analyzer
Picarro-G2207-i Isotope and Gas Concentration Analyzer
Product details
Product Overview
The Picarro G2207-i gas concentration and isotope analyzer combines high-precision and low drift O2 concentration measurements with analysis of δ 18O in ambient air, making it an ideal choice for challenging applications including atmospheric oxygen monitoring, to determine biogeochemical processes involved in the carbon cycle.
Product Features
Measure the concentration of O2 gas and δ 18O in the atmosphere
Two measurement methods: O2 concentration only mode and δ 18O+O2 concentration mode
Accuracy less than 2 ppm in O2 concentration mode
The maximum peak to peak drift at standard temperature and pressure is 6 ppm
Equipped with water measurement and calibration functions
