Carbon Dioxide Isotope Analyzer - Elevated CO2

LGR’s new “Carbon Dioxide Isotope Analyzer

- Elevated CO2“ provides many features that

researchers need when measuring isotopic

carbon dioxide from samples containing high

levels of CO2 including:

• LGR’sEnhancedPerformancepackage

provides ultra-low drift and high precision

• AbilitytomeasureCO2 as well as δ13C and

δ18O in CO2 from 2% to 100% CO

• Abilitytoanalyzeacidifiedcarbonates

• Abilitytoanalyzebreath(human,mice)

The stable isotope composition of carbonate

mineralshasbeenofinterestfordecades,with

initial research focusing on measurements of

carbonates in the ocean for paleoceanography

applications. Stable isotope studies of

carbonates have also been used extensively

toexploretheroleoffluid-rockreaction

and geosphere-hydrosphere-atmosphere

interactions in the earth and environmental

sciences.Todate,conventionalanalyses

LGR’s new “Carbon Dioxide Isotope Analyzer

- Elevated CO2“ provides measurements of

δ13C and δ18O as well as mixing ratios of13CO

2,12CO

with high precision in measurement times

oflessthanaminuteinaneasy-to-use,field

portable unit. Due to its inherently fast time

response,theinstrumentprovidesδ13C and

δ18O measurements over a wide range of

even when CO2 values change rapidly as often

happensduringfieldstudies.

The new Analyzer meets all of the needs for

effective measurements of isotopic carbon
