ABSTRACT:
Apparatus, and process, for extracting organic fluids and solids specimens from weighed amounts of semi-solids and solids samples for collection, concentration and transfer to an analytic unit. The organic specimen is picked up by a probe assembly from a single compartment septum-sealed vial by heating and slurrying the sample, contacting with a gas; and then transferring the organic specimen with the gas to a collection device, e.g., a syringe or adsorbent trap. The specimen is then transported to an analytical instrument for analysis.
