Abstract
The present invention provides a device that makes it possible to perform real-time detection and analysis of BTEX components in real samples using an inexpensive and miniaturized hybrid specific binding-separation device. The device may be used in occupational health and safety applications as well as for toxicological population studies to determine the presence of organic volatile components in an air sample.
Claims24
A device for the detection of chemical moieties in a gas sample, said device comprising:
- a. a flow control unit;
- b. a separation unit;
- c. a detection unit comprising at least one sensor comprising a coating of a sensing material that specifically detects the presence of said chemical moieties in said gas sample;
- wherein said flow control unit is operably linked to and controls the flow of a mobile gas phase through the separation unit;
- said separation unit is operably linked to said detection unit and separates the components in said gas sample and provides said separated components to said detection unit;
- and
- a sensor to provide a signal to a detection circuit that allows a qualitative and/or quantitative detection of said chemical moieties separated by said separation unit.
A method of detecting the presence of benzene, toluene, ethylbenzene and xylenes in a gas sample comprising performing a miniaturized gas chromatographic separation of said sample and detecting the presence of BTEX therein using a device of any of claims 1-24.
