Abstract
The present invention provides a device for detecting the presence of an analyte, such as for example, a lightweight device, including: a sample chamber having a fluid inlet port for the influx of the analyte; a fluid concentrator in flow communication with the sample chamber wherein the fluid concentrator has an absorbent material capable of absorbing the analyte and capable of desorbing a concentrated analyte; and an array of sensors in fluid communication with the concentrated analyte to be released from the fluid concentrator.
Claims45
A device for detecting the presence of an analyte, wherein said analyte is a microorganism marker gas indicative of a respiratory tract infection, said device comprising:
- a) a sample chamber having a fluid inlet port for the influx of said analyte;
- b) a fluid concentrator in flow communication with said sample chamber, said fluid concentrator having an absorbent material capable of absorbing said analyte and capable of desorbing a concentrated analyte;
- and
- c) an array of sensors in fluid communication with said concentrated analyte.
The device according to 1, claim further comprising a detector operatively associated with each sensor and providing a response in the presence of said analyte.
