• High vacuum pump (diffusion or turbo pump)
• Analyzer chamber
• Side plate (analyzer door), and front and rear end plates
• Vacuum seals
• Calibration valve(s) and vent valve
• Vacuum control electronics
• Vacuum gauges and gauge control electronics
Each of these is discussed in more detail in this chapter.
