Abstract
A spectroscopy system is disclosed, and includes a resonant cavity, a first conduit configured to couple at a first end thereof to a gas source, and at a second end thereof to a first end of a sorbent tube containing a sample for analysis, and a second conduit configured to couple at a first end thereof to a second end of the sorbent tube, and at a second end thereof to the resonant cavity.
Claims25
A spectroscopy system, comprising:
- a resonant cavity;
- a first conduit configured to couple at a first end thereof to a gas source, and at a second end thereof to a first end of a collection medium containing a sample for analysis;
- a second conduit configured to couple at a first end thereof to a second end of the collection medium, and at a second end thereof to the resonant cavity;
- and
- a heater positioned to heat the collection medium when the collection medium is coupled to the first conduit and to the second conduit.
2 more elements
A method of performing spectroscopy, comprising:
- coupling a gas source to a first end of a collection medium containing a sample for analysis;
- coupling a second end of the collection medium to a resonant cavity;
- heating the sorbent tube to a target temperature;
- and
- flowing gas from the gas source through the collection medium and into the resonant cavity.
2 more elements
The method according to 16, further comprising:
- measuring the pressure in the resonant cavity via a pressure sensor positioned upstream of the sorbent tube when gas is flowing from the sorbent tube to the resonant cavity.
A spectroscopy system, comprising:
- a resonant cavity having a first mirror positioned towards a first end thereof and a second mirror positioned towards a second end thereof and at least one interior surface extending between the first mirror and the second mirror, wherein the at least one interior surface is chemically inert.
