A Detection System with Low Sampling Distortion for Application in Optical Array Sensing in Gas Phase

An inexpensive hand-held device for analysis of fluorimetric sensor arrays has been developed. The device makes use of a web camera microcontroller to simultaneous acquisition of optical signal intensity from an array of fluorescent sensors at scan rates up to 11 Hz. The temperature control system address a problem of analyte adsorption on internal surfaces of the airway. Signal-to-noise ratios allow registering luminosity attenuation of fluorophores down to a 1.2 % from a single frame of observation.
