Book Description
A method is presented for using a mass spectrometer leak detector analytically for large systems. The method consists of calibrating the mass spectrometer, measuring the response time of the system being checked for leaks, and then utilizing these results in the system tests. The method has been used to measure leaks in two large (360 and 600 liters) heat exchangers of complex internal geometry. The response times of these vessels were 18 and 24 min, respectively, and the minimum detectable leak was about 4.6 x 10−10 std-cc/sec for each vessel.

Book Description
The measurement of leaks in vacuum components using helium mass-spectrometers is analyzed mathematically and the necessary conditions for using a simple expression for an 'integrated burst' method of increasing sensitivity, are discussed. (Author).
