Appeal No. 1996-1877
Application No. 08/149,716
APPENDIX
24. A method of preparing a volatile sample from a
material for gas chromatographic analysis, comprising:
introducing a vial with the material containing the
volatile
sample and a headspace therein into a chamber of a platen for
transporting the vial to a location for removal of at least a
portion of the volatile sample for gas chromatographic
analysis;
heating the material containing the volatile sample while
the vial is being transported to the location for removal;
agitating the vial while in the chamber to enhance a
transport rate of the volatile sample from the material to the
headspace of the vial; and
introducing a needle to the vial to withdraw at least a
portion of the volatile sample from the headspace of the vial.
29. A method of preparing for analysis by gas
chromatography a gaseous sample representative of an amount of
a volatile component contained in a material disposed in a
vial, the gaseous sample being contained in the vial in a
headspace above the material, comprising:
selecting a particular vial agitation intensity from a
source of variable vial agitation intensity;
placing the vial into a chamber of a platen;
heating the material while the vial is in the chamber;
agitating the material at the particular agitation
intensity by applying an oscillating motion to the vial;
transporting the vial to a sampling location by movement
of the platen while the vial remains in the chamber; and
