well-defined components, each of which contributes to
the overall chromatographic performance. Most of these
components have reached amature level of technical development
after nearly 50 years of development. Nonetheless,
advances are occurring in an evolutionary, not revolutionary,
manner with sample handling and in refinements of
detectors. One area of dramatic advance in GC instrumentation
is the development of small, sophisticated, portable
gas chromatographs. Each component of a gas chromatograph
(columns excepted) is discussed below where
principles and recent developments are emphasized.详细>
