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.


Offered here is a system for analyzing complex trace gas mixtures accurately and efficiently. Applications include:
• Process control,
• Forensics,
• Pharmacology
• Medicine,
• Environmental testing
• Fundamental science/laboratory work
Specific examples include [1] analyzing compounds in human breath, used as are markers of health risks, cancer, and environmental hazards. [2] analyzing human blood and urine to detect for any of hundreds of biologically important hormones; and so forth. or [3] analyzing organic amines and carboxylic acids present in nanomolar concentrations in seawater to provide a quantitative measure of marine ecosystem metabolic cycles.
