Analyzing trace gases at part-per-billion levels by rapid gas-phase cooling
This invention realizes a new idea of using buffer gas to rapidly cool small gas molecules to very low temperatures.
Intellectual Property Status: Patent(s) Pending
Offered here is a system for analyzing complex trace gas mixtures accurately and efficiently. Applications include:
• Process control,
• Environmental testing
• Fundamental science/laboratory work
Specific examples include  analyzing compounds in human breath, used as are markers of health risks, cancer, and environmental hazards.  analyzing human blood and urine to detect for any of hundreds of biologically important hormones; and so forth. or  analyzing organic amines and carboxylic acids present in nanomolar concentrations in seawater to provide a quantitative measure of marine ecosystem metabolic cycles.
