Title:

SENSING MATERIALS FOR SELECTIVE AND SENSITIVE DETECTION OF HYDROCARBONS AND ACIDS

Document Type and Number:

WIPO Patent Application WO/2011/140239

Kind Code:

A3

Abstract:

A method and apparatus including: 1) Synthesis of a sensing material with high density of binding sites and excellent selectivity for toxic hydrocarbons and acid vapors; 2) Coating of the sensing material onto the surface of sensors, such as quartz crystal tuning forks; and 3) integration of the coated sensors with proper sample conditioning unit. The device achieves high sensitivity and selectivity, and has been tested in various field environments.
