Abstract
The present disclosure is directed to methods and systems for detecting a chemical substance. The methods and systems include using gas-solid phase chemistry to chemically and/or physically modify a substance of interest so that the substance can be vaporized and detected through an analysis of the substance.
Claims20
A method for detecting a substance of interest, the method comprising:
- collecting a sample of a substantially non-volatile substance of interest on a sampling trap;
- inserting the trap into a thermal desorber;
- introducing a vaporized clustering agent into the desorber, wherein the clustering agent increases the volatility of the substance of interest;
- vaporizing the substance of interest;
- transferring the vaporized substance of interest into a detector;
- performing an analysis of the substance of interest;
- and,
- detecting the substance of interest.
5 more elements
A method for detecting a substance of interest, the method comprising:
- increasing the volatility of a substantially non-volatile substance of interest, wherein the volatility of the substance of interest is increased by applying a vaporized clustering agent to the substance of interest;
- vaporizing the substance of interest in a thermal desorber;
- and,
- transferring the vaporized substance of interest into a detector, wherein the detector performs an analysis of the vaporized substance of interest and detects the substance of interest.
1 more element
A substance detection system, the system comprising:
- a sampling trap including a substantially non-volatile substance of interest;
- a housing including a clustering agent, the housing configured to vaporize the clustering agent;
- a thermal desorber configured to receive the sampling trap, wherein the desorber is configured to vaporize the substance of interest;
- a transfer line, wherein the transfer line connects the housing to the desorber and transfers the vaporized clustering agent from the housing to the desorber, wherein the vaporized clustering agent increases the volatility of the substance of interest;
- an analysis device coupled in flow communication with the desorber, the analysis device configured to receive the vaporized substance of interest from the desorber and perform an analysis of the substance of interest.
