Abstract
A sampling apparatus includes a wand extension coupled with a trace detection head and a bulk detection head. The trace detection head collects a maximum amount of a sample for a trace detection analysis. The bulk detection head collects a minimal amount of a substance for use in bulk sample identification.
Claims28
A sampling apparatus for a chemical analyzer comprising:
- a wand extension having ends coupled with a trace detection head and with a bulk detection head;
- wherein the trace detection head comprises:
- a body for receiving a swab support and configured for coupling with the wand extension;
- a retaining ring for coupling a swab to the body of the trace detection head, wherein the body of the trace detection head has a groove for receiving a shuttle that is connected to the retaining ring;
- and
- a resistive heating element to heat a swab,
- wherein the bulk detection head comprises:
- a body for receiving a bulk collector, wherein the bulk collector comprises a base with a resistive heating element and a member that extends perpendicular from the base of the bulk collector.
