Patent number: 11917744Abstract: A system for cooling an inductively coupled plasma (ICP) instrument includes: the ICP instrument; a pump in fluid communication with the instrument via a first conduit; and a micro-channel heat exchanger in fluid communication with the instrument via a second conduit, and in fluid communication with the pump via a third conduit. The pump is configured to generate a pump outlet pressure of coolant that exceeds a back pressure of the instrument such that a pressure of the coolant traveling through the second conduit and into the heat exchanger is less than or equal to 5 pounds per square inch (psi) above atmospheric pressure, as measured at an inlet to the heat exchanger.Type: GrantFiled: July 22, 2021Date of Patent: February 27, 2024Assignee: PERKINELMER SCIENTIFIC CANADA ULCInventors: Tak Shun Cheung, Chui Ha Cindy Wong, William Fisher, Hamid Badiei

Publication number: 20200149525Abstract: A method for pumping a fluid includes providing a peristaltic pump including a contact wall, an opposing, movable compression element, and a flexible tube interposed between the contact wall and the compression element in a compressing region. The flexible tube has a tube lengthwise axis and a through passage. The flexible tube is displaceable relative to the compressing region between a first position and a second position different from the first position. The method includes: with the flexible tube in the first position, compressing the flexible tube between the compression element and the contact wall to thereby force the fluid through the through passage; thereafter displacing the flexible tube into the second position from the first position; and thereafter, with the flexible tube in the second position, compressing the flexible tube between the compression element and the contact wall to thereby force the fluid through the through passage.Type: ApplicationFiled: January 21, 2020Publication date: May 14, 2020Inventors: Tak Shun Cheung, Chui Ha Cindy Wong, Andrew Icasiano
