| titleOfInvention | Gas detection device and method |
| abstract | Improved method and apparatus for detecting vapor or ionizable gas which can in preferred embodiments sample at least 4 x 10-3 cubic meters of air per sec-1 and responds to fluctuations in ionizable gas at a lower velocity or equal to 100 Hz. It has been found that the use of the device of this invention confers a sensitivity to vapor or gas ionizable by ultraviolet rays exceeding 500 times that of the devices of the prior state of the art and makes it possible to detect propylene tracer gas at concentrations of 2 parts per 1,000,000,000 thereby increasing the distance from the gas source with which the device can be reliably operated. This invention also relates to the use of this device for detecting leaks of volatile compounds which can be ionized by U.V. rays and for monitoring processes in which vapors are emitted. |
