Equipment to measure carbon isotopes
WebThe Picarro G2201-i CRDS analyzer is capable of simultaneous measurement of carbon isotopes from both CO2 and CH4. The G2201-i operates in one of three modes: CO2-only mode, CH4-only mode, and combined CO2/CH4 mode. The Small Sample Isotope Module 2 (SSIM2) expands the measurements that can be made with the Picarro δ13C … WebThe isotope-ratio mass spectrometer (IRMS) allows the precise measurement of mixtures of naturally occurring isotopes. Most instruments used for precise determination of isotope ratios are of the magnetic …
