.~.~ Using electronegative gas sensor
DEFINITION
Classification: 324/465
Using electronegative gas sensor:
(under subclass 464) Subject matter wherein a gas whose molecules exhibit electron affinity or an ability to pick up free electrons and form negative ions, is sensed.
(1) Note. These types of sensors normally utilize an ionization source to ionize a carrier gas in which the electronegative gas is present.
(2) Note. These devices are often called electron capture detectors.
(3) Note. Some examples of electronegative gases are O2, HCL, SO2, C12 and Freon gas.
