Abstract:
An apparatus for detection of at least one volatile product in a sample which comprises:(a) a circuit comprising (i) one or more gas-detecting transducer means mounted in a confined space for containing the sample which detects the volatile product produced from the sample to produce a first analog signal, (ii) a temperature-detecting transducer means mounted in the confined space for containing the sample which detects temperature in the confined space to produce a second analog signal, and (iii) a humidity-detecting transducer means mounted in the confined space containing the sample which detects humidity in the confined space to produce a third analog signal; (b) an analog to digital conversion means in the circuit for converting the first, second, and third analog signals to digital signals; and (c) an acquisition means in the circuit which stores the digital signals resulting from the analog signals in memory as detectable signals and retrieves the detectable signals to provide the detection of the volatile product, the temperature, and the humidity wherein the volatile product in the confined space is detected over time to produce a distinctive signature as a graph of the volatile product in the confined space and wherein the temperature and the humidity in the confined space are detected over time to produce a graph of the temperature and humidity in the confined space.
