REFERENCING AND RAPID SAMPLING IN ARTIFICIAL OLFACTOMETRY |
摘要 |
Devices and methods are disclosed that are effective to produce reliable vapor measurements in the presence of drift. In certain instances the sensor module (14) is mounted externally on a housing. In other instances, the sensor module (14) contains a first sensor element incorporating a first array of sensors and a second element incorporating a second array of sensors and both sensor elements are mounted externally on the housing. The present invention relates to mapping an x-y surface for detection of an analyte, includes moving in tandem at least two sensor arrays separated by a distance "d" across an x-y surface to produce a plurality of responses and analyzing the responses to map the x-y surface for detection of an analyte. Moreover, a sensor module (14) is provided, such as in a handheld device (10), comprising at least two pneumatic vapor paths and at least two sensor arrays. The dual pneumatic train allows rapid sensing as it increases the duty cycle frequency. |
