  • Patent number: 10953345
    Abstract: A sample dispatcher is disclosed and is configured for individually introducing a plurality of portions of one or more sample fluids into a flow of a mobile phase of a liquid separation system. The liquid separation system is configured for separating compounds of the sample fluids and comprises a mobile phase drive configured for driving the mobile phase through a separation unit configured for separating compounds of the sample fluids in the mobile phase. The sample dispatcher comprises one or more sample reservoirs, each configured for receiving and temporarily storing a respective sample fluid portion or at least a part thereof, and a bypass channel.
    Type: Grant
    Filed: April 14, 2014
    Date of Patent: March 23, 2021
    Assignee: Agilent Technologies, Inc.
    Inventors: Klaus Witt, Konstantin Shoykhet, Dwight Stoll
  • Patent number: 10281058
    Abstract: A fluid processing device (10) for processing fluid, wherein the fluid processing device (10) comprises a first fluid drive unit (20) configured for driving a first fluid along a first flow path (85), a second fluid drive unit (20?) configured for driving a second fluid along a second flow path (86), and a fluidic switch (90) fluidically coupled to the first flow path (85) and to the second flow path (86) and configured for being switchable for transferring first fluid from the first flow path (85) into the second flow path (86) without interruption of fluid flow along at least one of the first flow path (85) and the second flow path (86).
