Vacuum Quality Measurement System

A gas analyzer for a vacuum chamber includes processing electronics configured to receive mass spectral data, receive input of total pressure in the vacuum chamber, receive external input from at least one sensor, and employ the mass spectral data, the total pressure in the vacuum chamber, and the e...

description A gas analyzer for a vacuum chamber includes processing electronics configured to receive mass spectral data, receive input of total pressure in the vacuum chamber, receive external input from at least one sensor, and employ the mass spectral data, the total pressure in the vacuum chamber, and the external input from the at least one sensor to calculate a vacuum quality index based on at least one criteria of quality.
