6.3 Test Method C is to be used only when there is no convenient method of connecting the leak detector to the outlet of the high vacuum pump. If a helium leak detector is used and the high vacuum pump is an ion pump or cryopump, leak testing is best accomplished during the roughing cycle as these pumps leave a relatively high percentage of helium in the high vacuum chamber.

2019-5-25The reactions of 23 transition metal ions M+(g) with phosphane (PH3) have been investigated using Fourier transform ion cyclotron resonance spectrometry. Two main reaction pathways are observed, sequential dehydrogenation of multiple (up to nine) phosphane molecules, and addition of multiple (up to four) phosphane molecules. The addition and dehydrogenation reaction pathways are, …

Gas detectors are used to measure and indicate the concentration of various gases in air and can be used as an early detection system against increase in concentration of life threatening gases such as carbon dioxide (CO2), carbon monoxide (CO) and ammonia (NH3) apart from combustible gases. A large number of industries are involved in the use of combustible and toxic gases or product high ...
