Abstract:
A sample injector for use in a fluid separation system for separating compounds of a fluidic sample in a mobile phase, the sample injector comprising a switchable valve, a sample loop in fluid communication with the valve and configured for receiving the fluidic sample, a metering device in fluid communication with the sample loop and configured for introducing a metered amount of the fluidic sample on the sample loop, and a control unit configured for controlling switching of the valve to transfer the sample loop between a low pressure state and a high pressure state via an intermediate state and for controlling the metering device during the intermediate state to at least partially equilibrate a pressure difference in the sample loop between the low pressure state and the high pressure state.

Claim (Index 2):
A method of injecting a sample in a liquid chromatography system, the method comprising:\n isolating a sample loop of the liquid chromatography system from a high-pressure fluidic path of the liquid chromatography system, the high-pressure fluidic path at a pump pressure in fluid communication with a liquid chromatography column of the liquid chromatography system, wherein the high-pressure fluidic path is at a pump pressure, wherein the sample loop comprises a metering device for loading a sample into the sample loop, wherein a volume of the metering device is defined by a cavity in which a metering piston is slidably mounted; determining a movement of the metering piston within the cavity from a first position to a second position to increase a pressure in the sample loop from an essentially ambient pressure to the pump pressure based on the pump pressure; loading the sample in the sample loop; with the sample placed in the sample loop and with the sample loop remaining isolated from the high-pressure fluidic path, decreasing the volume of the metering device to increase the pressure in the sample loop from the essentially ambient pressure to essentially correspond to the pump pressure of the high-pressure fluidic path, wherein the movable element within the cavity is moved between the determined positions from the first position to the second position; and connecting the sample loop to the high-pressure fluidic path so that the pump pressure from a high-pressure pump is applied to the sample loop to cause the sample in the sample loop to flow from the sample loop through a portion of the high-pressure fluidic path to the chromatography column.
