Development of a Miniature Gas Chromatograph (µCAD) with Sample Enrichment, Programmed Temperature GC and Plasma Emission Detection (PED)

A miniature gas chromatograph is described having the following key features: a miniaturized chemical trap for enrichment, rapid thermal desorption of the trap, a resistively heated capillary column for programmed GC analysis, and a micro-chip based plasma emission detector (PED).
