Improved capsule injection system for gas chromatography

The present invention includes a heat scalable capsule [41] adapted for use in analysis devices such as GCs, and methods for using the capsules to perform analysis in such devices. The capsules[41] include a tube[11] having an end that is heat-sealed to contain a sample that is to be analyzed at an injection temperature. The tube[11 ] includes a heat scalable medium[12] having a heat seal that closes the end, the tube [11] having an inner and outer surface, both of the surfaces being substantially chemically inert with respect to the sample. The tube [11] is substantially free of any material that outgases at the injection temperature. The capsule[41] is openable without breaking into pieces, and remains intact at the injection temperature. The capsule can include a programmable tag[63] that stores information related to the sample contained therein.
