title: An all-purpose injection system for gas chromatographic analyses of biological samples.
abstract: A versatile injection system for the direct introduction of samples into the gas chromatograph (GC) is described. Several years of experience in biological and pharmaceutical chemistry have led to the construction and final modification of this device. No modification of the injection port of the GC is necessary.
