Publication number: 20230197431Abstract: Systems and methods for use in introducing samples to an analytical device for single particle compositional analysis. Suitable analytical devices include, for example, an inductively coupled plasma-optical emission spectrometer. Prior to introduction to the analytical device, the sample gas is exchanged with argon gas, for example, using a gas exchange device. The analytical device may be calibrated with a liquid sample which is aerosolized prior to entry into the analytical device.Type: ApplicationFiled: February 13, 2023Publication date: June 22, 2023Inventor: Chady Stephan

Patent number: 11315778Abstract: Devices, systems and methods including a spray chamber are described. In certain examples, the spray chamber may be configured with an outer chamber configured to provide tangential gas flows. In other instances, an inner tube can be positioned within the outer chamber and may comprise a plurality of microchannels. In some examples, the outer chamber may comprise dual gas inlet ports. In some instances, the spray chamber may be configured to provide tangential gas flow and laminar gas flows to prevent droplet formation on surfaces of the spray chamber. Optical emission devices, optical absorption devices and mass spectrometers using the spray chamber are also described.Type: GrantFiled: September 18, 2020Date of Patent: April 26, 2022Assignee: PerkinElmer Health Sciences Canada, Inc.Inventors: Chady Stephan, Hamid Badiei, Serguei Savtchenko, Samad Bazargan
