摘要： Provided herein is a sample injection method that enables efficient injection of a trace sample solution while reducing the measurement time. A sample solution is injected into a sample loop with air layers disposed on both sides of the sample solution, and the total amount of the sample solution, including the air layers, is injected into a detector. The start and the end of data collection are determined from the detection signal intensity changes that occur upon the air layers being injected into the detector, and the velocity of the flowing liquid is increased to reduce the measurement time. A washing solution is injected after the air layer to improve the washing efficiency and reduce the washing time.

摘要： An injector, for injecting a fluidic sample into a flow path between a fluid drive and a sample separation unit, includes a sample accommodation volume, a sample drive, and a fluidic valve switchable to selectively couple the volume with the flow path or decouple the volume from the flow path. In an injection switching state, the fluid drive, the separation unit and the sample drive are coupled by the valve so that fluid driven by the sample drive and flowing from the volume to the separation unit and further fluid driven by the fluid drive and flowing from the fluid drive to the separation unit are combined at a fluidic connection upstream of the separation unit. A control unit controls a pressure of the fluid and/or the further fluid during injecting.

摘要： A multi-dimensional liquid analysis system includes a first dimension system and a second dimension system, wherein outflow from the first dimension system is separated at a flow splitter under controlled conditions. The flow splitter separates the first dimension outflow into first and second split outlet flows, with one of the split outlet flows being metered to a designated flow rate with a flow metering device disposed downstream from the flow splitter. The flow metering device selectively closes or opens an outlet flow path to define a volumetric flow rate along that outlet flow path, so that the other split outlet flow is correspondingly controlled.

摘要： A method and a system for introducing a sample into a mobile phase of a chromatography system is provided. The method includes initially directing the mobile phase directly into a separation unit of the chromatography system, bypassing a sample loop, the mobile phase including a combined solvent, metered from a pressurized first solvent and a second solvent; loading the sample into the sample loop, while the mobile phase continues to be directed directly into the separation unit; pressurizing the sample in the sample loop with the pressurized first solvent, while the mobile phase continues to be directed directly into the separation unit; and switching the sample loop into the mobile phase, thereby introducing the pressurized sample to the separation unit.
