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.
