Abstract
The amount of extraneous gas within a hermetic sealed package, such as water vapor, is measured by measuring the total gas pressure within the package. This gas pressure is compared to a correlation made of expected total pressure within a package to deviations to that total pressure to determine the amount of extraneous gas. The correlation itself is derived statistically by comparing samples of actual total pressure to expected total pressure. These samples are then used to statistically produce the above correlation which is then used in actual testing.
