In addition to the need to process large quantities of samples that technology produces more and more prolihcally, the demand for faster analytical response is also borne from applications where analysis time is inherently critical, as with first-responders and held soldiers sampling the air to check for the presence of chemical warfare agents (CWA). DARPA (Defense Advanced Research Projects Agency), which commissions advanced research for the Department of Defense, is funding the development of micro gas analyzers (MGA) suitable for portable and virtually instant CWA detection. 

The sensitivity and selectivity of gas chromatography make it a strong fimdamen-tal technology for addressing DARPA s needs in the area of CWA detection. No other spectrometric analyzer offers to separate the components of a mixture and then make small amounts of them available for further identification and quantification. However, current GC systems are unacceptably large and slow for the envisioned applications.
