Glass capillary gas chromatography (GC)/sup 2/, represents a new era of chromatographic separation techniques and capabilities which is expected to become the most commonly used method of doing gas chromatography in the near future. Although the concept of capillary column chromatography was first described by Golay in 1957, the technique is only now becoming reliable, reproducible, accurate and amenable to routine use in analytical laboratories. Since 1957, a great deal of technology has been developed to bring GC instruments, techniques, and thin film glass capillary columns up to the point where these systems are a) highly efficient, b) more reproducible than packed column separations, c) chemically inert, and d) thermally stable. Special techniques, injectors, detectors, accessories, and instrumentation are now available for doing (GC)/sup 2/, and the literature contains a large number of papers demonstrating the proven capabilities of the technique. Further, the need exists now, more than ever, in trace organic analysis for analytical techniques which are capable of separating increasingly complex samples and analyzing them at trace levels. Only (GC)/sup 2/ has that total capability today. To illustrate a few of the problems in trace organic analysis being solved today by (GC)/sup 2/, examples are presented to illustrate the diversity and power of the technique in solving difficult separation and analysis problems.
