Method and Apparatus for Detection, Identification and Quantification of Chemical or Biological Material through Modification of Operating Conditions

摘要

A sensors reading when exposed to different chemical compounds changes if an operating condition of the sensor such as temperature, pressure, electromagnetic field intensity, light or radiation level is modified and the amount of change is different for different compounds. This invention uses this phenomenon to identify and quantify the concentration of the compound.

主权项

1. We identify compounds from each other using a sensor that is sensitive to those compounds and has different sensitivity to those compounds under different operating conditions by taking multiple readings under different operating conditions.
