- W63847587 abstract "A new technique for measuring the accumulated gas that leaks through a silica membrane helium leak has been developed. Though the basic principle of gas accumulation into a known volume is employed, the present method differs from that of others in that a mass spectrometer is utilized for the purpose of sensing only helium, while discriminating against all other outgassed materials thereby providing a distinct advantage over the use of the conventional ion gauge, McLeod gauge, and other total-pressure measuring devices. The test apparatus fabricated for this investigation exhibited no tendency to “hang up” on helium, and pumped “helium-free” after each test, thereby eliminating the necessity for zero corrections, etc. Results obtained indicate that the overall accuracy achieved by using this technique and equipment was ±10 per cent of the actual leak rate for leaks ranging from 2 × 10-9atm-cm3/sec*of helium to 1 × 10-6 atm-cm3/sec of helium. On the basis of the work recently completed, it seems feasible to measure leaks in the range of 1 × 10-11 atm-cm3/sec of helium." @default.
