Abstract
The present disclosure is directed to methods and systems for detecting a substance of interest. The methods and systems include collecting the substance of interest on a collection device comprising an inert fiber material and a siloxane resin. The systems and methods further include heating the collection device in a desorber, wherein heating the device releases the substance of interest from the device, performing an analysis of the substance of interest, and detecting the substance of interest.
Claims17
A system for detecting a substance of interest, the system comprising:
- a collection device comprising an inert fiber material and a siloxane resin, wherein the collection device is configured to collect a substance of interest wherein the siloxane resin comprises at least one substituent selected from the group consisting of methyl groups, phenyl groups, and hydroxyl groups, and wherein a flexibility of the collection device is adapted to decrease as a ratio of phenyl groups to methyl groups in the siloxane resin increases;
- an inlet configured to receive the collection device including the substance of interest;
- a desorber configured to heat the collection device to release the substance of interest;
- and
- an analysis device coupled in flow communication with the inlet and the desorber, wherein the analysis device is configured to perform an analysis on the substance of interest.
A system for detecting a substance of interest, the system comprising:
- a collection device comprising an inert fiber material and a siloxane resin, wherein the collection device is configured to collect a substance of interest, wherein the siloxane resin has a general chemical structure [(Si(Me2)-O-)x(Si(Ph2)-O-)y(Si(R2)-O-)z], wherein R is independently selected from a hydroxyl group and an alkyl group, and wherein x, y, and z are integers;
- an inlet configured to receive the collection device including the substance of interest;
- a desorber configured to heat the collection device to release the substance of interest;
- and
- an analysis device coupled in flow communication with the inlet and the desorber, wherein the analysis device is configured to perform an analysis on the substance of interest.
