Portable device for detecting UV light ionizable gas or vapor |
| abstract |
An improved ionizable gas or vapor detector device and method are provided which are capable in preferred forms of sampling 4×10 -3 cubic meters or more of air sec -1 and are responsive to ionizable gas fluctuations at a rate of up to 100Hz. Use of the device of the present invention has proved to provide sensitivity to UV ionizable gas or vapor of over 500 times that of prior devices, giving detection of propylene tracer gas at concentrations of 2 parts per 1,000,000,000 and thus increasing the range from the gas source at which the device may be reliably used. Use for detection of leaks of volatile UV ionizable compounds and for monitoring processes where vapors are emitted is also provided. |
