Patent number: 11948785Abstract: The present invention relates to electron multiplier apparatus of the type used in ion detectors. In one form, the invention is an electron multiplier having two or more electron emissive surfaces, each having a different composition so as to together limit or overcome an acute gain effect on the electron multiplier due to the exposure of the two or more electron emissive surfaces to water molecules. Alternatively, the multiplier may have a single electron emissive surface of mixed composition comprising a first composition component and a second composition component so as to together limit or overcome an acute gain effect on the electron multiplier due to the exposure of the electron emissive surface to water molecules.Type: GrantFiled: August 10, 2021Date of Patent: April 2, 2024Assignee: ADAPTAS SOLUTIONS PTY LTDInventors: Aditya Wakhle, Russell Jurek, Kevin Hunter

Publication number: 20230215712Abstract: Scientific analytical equipment including apparatus and methods for detecting and quantitating particles, and particularly ions generated in the course of mass spectroscopy. In one version, a particle detection apparatus includes electron emissive surfaces which emit secondary electrons in response to impact with a particle, the apparatus maintaining spatial separation between: (i) secondary electrons emitted as a result of the impact of a first particle in a first region of the electron emissive surface; and (ii) secondary electrons emitted as a result of the impact of a second particle in a second region of the electron emissive surface.Type: ApplicationFiled: June 7, 2021Publication date: July 6, 2023Inventors: Russell Jurek, Toby Shanley

Publication number: 20230015584Abstract: Scientific instruments (such as mass spectrometers) include an electron multiplier and a cross-filed ion detector including an ion impact plate. The electron multiplier receives and amplifies secondary electrons emitted by the impact plate to generate an output signal. The output signal is amplified and subsequently digitized. Amplification is limited so as to keep secondary electrons to a maximum thereby decreasing electron flux and improving instrument life.Type: ApplicationFiled: December 7, 2020Publication date: January 19, 2023Inventor: Russell Jurek
