Technology Marketing Summary

In many sealed systems, the spontaneous generation of chemicals and gases can adversely affect the contents of a sealed system. The container or system is closed, and sampling is impossible. A passive method for detecting the presence of specific chemicals in the system is critical and addresses a key question: How do you ascertain the integrity of the contents in a sealed container without opening it? This invention allows a sealed system to be monitored for the infiltration or generation of gases or other chemical species specific to the enclosed materials.

Description

The sensor can be used as a passive or active detector. It allows a specific gas or chemical to be specifically identified but also can determine its concentration, mass, temperature, and time history. The sensor provides quantitative analysis for determining longevity of the system.

Benefits
  • Can be custom tailored to react to a single chemical or broad spectrum of chemicals
  • Passive Monitoring
  • Cost-effective
Applications and Industries
  • Specialized storage and warehousing
  • Laboratory testing services
  • Scientific research and development
More Information

TRL 2: Applications are speculative at this time, however, key principles have been observed, and next steps include integrating into a functional prototype.

Passive in-situ chemical sensor
A chemical sensor for assessing a chemical of interest. In typical embodiments the chemical sensor includes a first thermocouple and second thermocouple. A reactive component is typically disposed proximal to the second thermal couple, and is selected to react with the chemical of interest and generate a temperature variation that may be detected by a comparison of a temperature sensed by the second thermocouple compared with a concurrent temperature detected by the first thermocouple. Further disclosed is a method for assessing a chemical of interest and a method for identifying a reaction temperature for a chemical of interest in a system.
