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 15):
A method of operating a liquid chromatography system, the liquid chromatography system comprising a liquid chromatography column and an injection valve, the method comprising:\n isolating a sample loop of the liquid chromatography system from a high-pressure fluidic path in fluid communication with the liquid chromatography column, wherein the high pressure fluidic path is at a pump pressure, wherein the sample loop is in fluid communication with the injection valve and the sample loop comprises a metering device for loading a sample into the sample loop, and isolating the sample loop comprises placing the injection valve in a PRESSURE COMPENSATION position, wherein the metering device comprises a chamber and a piston in the chamber; determining a movement of the piston within the chamber 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; and while the sample loop is isolated from the high-pressure fluidic path, forwarding the piston within the chamber from the first position to the second position 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.
