Patent number: 10399078Abstract: Apparatuses, components, methods, and systems for interrogating samples are provided. An example system includes a flow cell. An example flow cell includes an aperture, an inlet chamber, and a sample injector positioned within the inlet chamber. An example sample injector is configured to generate a sample stream that flows in biased proximity to a profile included in the inlet chamber. An example method includes the steps of causing sheath fluid to flow into an inlet chamber and through an aperture, injecting sample into an inlet chamber with a sample injector to form a sample stream that is entrained in the sheath fluid, and interrogating the sample stream as the sample stream passes through an interrogation region within the aperture. An example sample injector includes an outlet that is disposed in an off-center position within the inlet chamber.Type: GrantFiled: June 5, 2015Date of Patent: September 3, 2019Assignee: Beckman Coulter, Inc.Inventors: Richard A.
