Publication number: 20240038521Abstract: An electrostatic lens for transporting charged particles in an axial direction includes a first group of first electrodes configured to receive a first DC potential from a DC voltage source, and a second group of second electrodes configured to receive a second DC potential from the DC voltage source different from the first DC potential. The first electrodes are interdigitated with the second electrodes. The first group and/or the second group has a geometric feature that progressively varies along the axial direction. The lens generates an axial potential profile that progressively changes along the axial direction, and thereby reduces geometrical aberrations. The lens may be part of a charged particle processing apparatus such as, for example, a mass spectrometer or an electron microscope.Type: ApplicationFiled: October 12, 2023Publication date: February 1, 2024Applicant: AGILENT TECHNOLOGIES, INC.Inventors: Tong CHEN, Curt A.

Publication number: 20230055007Abstract: An ion guide includes electrodes elongated along an axis from an entrance end to an exit end and spaced around the axis to surround an interior. The electrodes have polygonal shapes with inside surfaces disposed at a radius from the axis and having an electrode width tangential to a circle inscribed by the electrodes. An aspect ratio of the electrode width to the radius varies along the axis. The electrodes are configured to generate a two-dimensional RF electrical field in the interior having a multipole composition comprising one or more lower-order multipole components and one or more higher-order multipole components and varying along the axis in accordance with the varying aspect ratio, and having an RF voltage amplitude that varies along the axis.Type: ApplicationFiled: October 27, 2022Publication date: February 23, 2023Applicant: AGILENT TECHNOLOGIES, INC.Inventors: Tong CHEN, Gershon PERELMAN, Curt A.

Publication number: 20230009117Abstract: Methods and devices for extracting an internal pipe/tube element from a connected outer pipe/tube element. Certain embodiments are directed to methods and devices that inwardly distort a pipe/tube at a connection to allow the pipe to be more easily disconnected without damaging the overlapping (outside) half of the connection. Collapsing the pipe adjacent to, and into, the fitting and reducing its circumference allows the pipe to be unscrewed or slide out of the overlapping side of the connection. Embodiments are described including partially cutting thru the male portion of the connection and locally compressing and collapsing the pipe to radially disengage it from interior of the opposing fitting or pipe section. In one method, an interior pipe/tube is disengaged from a fitting or overlapping connection where a connection (weld, adhesive or soldered attachment) is utilized and the connection is selected small/weak enough to be broken in the compression process.Type: ApplicationFiled: July 4, 2022Publication date: January 12, 2023Inventors: Glen R. Stevick, Gershon Perelman, Kyle McGrath

Patent number: 10145753Abstract: A rotor is statically or dynamically balanced by driving the rotor to rotate at a desired speed, measuring an imbalance in the rotor, calculating an adjustment to be made in a mass distribution of the rotor based on the measured imbalance, and adjusting the mass distribution to reduce the imbalance. Mass adjustment is done by operating a laser to ablate material from the rotor according to operating parameters based on the adjustment calculated. The foregoing is done while the rotor is rotating.Type: GrantFiled: September 16, 2015Date of Patent: December 4, 2018Assignee: Agilent Technologies, Inc.Inventors: Gershon Perelman, Bartly Carlson

Patent number: 10010884Abstract: A droplet-based microfluidic device having a first confining plate, a second confining plate, and an actuator. Each confining plate includes a respective substrate and hydrophobic layer having a planar major surface. The first confining plate additionally includes a common electrode between its hydrophobic layer and substrate. The second confining plate includes an electrode array between its hydrophobic layer and substrate. The confining plates are disposed opposite one another with their major surfaces separated from one another by a gap. The actuator is to impart oscillatory sliding motion between the confining plates in a direction principally parallel to the major surfaces. The oscillatory sliding motion effectively allows voltages applied between the common electrode and the electrodes of the electrode array to move a microfluidic droplet located in the gap across the major surfaces without sticking.Type: GrantFiled: January 14, 2014Date of Patent: July 3, 2018Assignee: Agilent Technologies, Inc.Inventors: Curt A. Flory, Arthur Schleifer, Gershon Perelman

Patent number: 9589775Abstract: A mass spectrometry (MS) system may be cleaned by generating plasma and contacting an internal surface of the system to be cleaned with the plasma. The system may be switched between operating in an analytical mode and in a cleaning mode. In the analytical mode a sample is analyzed, and plasma may or may not be actively generated. In the cleaning mode the plasma is actively generated, and the sample may or may not be analyzed.Type: GrantFiled: July 30, 2015Date of Patent: March 7, 2017Assignee: Agilent Technologies, Inc.Inventors: Gershon Perelman, Mark Denning, Mehrnoosh Vahidpour, Guthrie Partridge

Patent number: 9449805Abstract: A charged particle processing apparatus includes a vacuum chamber, an optics plate, charged particle optics mounted to the optics plate, and mounting members coupled between the optics plate and a chamber wall. The mounting members are configured for isolating the optics plate from deformation of the chamber wall, as may occur due to a pressure differential between the chamber interior and the environment outside the chamber. The isolation may prevent deformation from affecting the alignment and positioning of the charged particle optics. The charged particles may, for example, be ions or electrons. Thus, the apparatus may be utilized, for example, in analytical instruments such as for mass spectrometry, or inspection instruments such as for electron microscopy.Type: GrantFiled: September 23, 2014Date of Patent: September 20, 2016Assignee: Agilent Technologies Inc.Inventor: Gershon Perelman
