FT-IR Gas Analysis with micro-volume gas cell

Jay Roberts, Thermo Fisher (US)

FT-IR spectroscopy provides a powerful, convenient approach to the analysis of multiple gas components, monitoring changes in composition over time spans of seconds, minutes, or hours.  It is used extensively to identify and quantify gas samples across many applications, including CEM, specialty chemicals production, and catalytic research.

Of current interest is use of FT-IR to monitor reaction chemistries in fuel cell research, where low-level contaminants can poison the reactive/catalytic electrode surfaces.  The low volume of gas products generated by these reactions, often only millimeters per minute, creates a challenge for FT-IR analysis, which typically require larger gas cells to attain the minimum detection limits required by researchers.

This (lecture/poster) will present data collected using a new configuration of an FT-IR with an ultra low-volume gas cell, with emphasis on sampling rates, llimits of detection, and practical sampling considerations.
