The blockage is detected as a result of a reduction in pressure within the vacuum chamber. This change in pressure is detected indirectly by monitoring the amount of power that a vacuum pump is using, the amount of current that a vacuum pump is drawing, the temperature of a vacuum pump or a region in proximity to the vacuum pump, or the flow rate of gas out of a vacuum pump."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automated cleanliness diagnostic for mass spectrometer","description":"A mass spectrometer or ion mobility spectrometer is disclosed comprising means for detecting a blockage in an inlet orifice arranged between an ion source and a vacuum chamber.
