PreCon Automated Trace Gas pre-Concentrator
Thermo Scientific PreCon allows sample sizes to be reduced by three orders of magnitude and improves sample throughput by at least one order of magnitude.
The PreCon is a fully automated trace gas pre-concentrator for the isotope characterization of N2O and CH4 at natural concentrations and natural isotope abundances.
N2O and CH4 are trace gases that are increasing in the atmosphere, contributing to the greenhouse effect. N2O also affects the global ozone distribution. Monitoring the concentrations of these gases in the atmosphere has given insight into the overall global budget, but monitoring the isotope ratios of these trace gases is required for a detailed understanding of their sources.
Isotope ratio analysis of these gases has been hampered by the necessity of collecting and manually processing very large sample volumes (e.g. 70 L of air for a 13C/12C measurement of CH4).
