ABSTRACT:
A compliant column sheath assembly for use in a gas chromatograph is provided which includes an open tubular column in the form of a helical coil having a coiled length of between about 5 and 15 cm. The sheath assembly further includes an insulating sheath which surrounds the open tubular column and a frame. When incorporated in a gas chromatograph, the compliant column sheath assembly allows samples to be analyzed in about 2 to 10 seconds.
