Disclosed is a sample injector (40) for individually introducing a plurality of portions of one or more sample fluids (200) into a flow of a mobile phase (210) of an HPLC system (10). The separation system (10) comprises a pump (20) for driving the mobile phase through a chromatographic column (30). The injector (40) comprises a plurality of sample reservoirs (310, 320), such as sample loops, each configured to receive and temporarily store a respective sample fluid portion or at least a part thereof. The sample injector (40) is configured such that in a first state, it can selectively couple one of the sample reservoirs (310, 320) between the pump (20) and the column (30), and in a second state, can couple at least two of the sample reservoirs (310, 320) in parallel between the pump (20) and the column (30). |
