Abstract

A system and method for the monitoring of carbon dioxide (CO2) for chemical contaminants. The carbon dioxide monitoring system includes a contaminant sensor that is configured to detect trace amounts of contaminants in CO2 that is pumped through it in real time. The contaminant sensor includes an interferometer configured to track the amount of contaminants.
