Abstract: A fluid transfer valve has ports arranged in groups. The valve has a rotor having channels and an actuator is operably connectable to the rotor. The actuator is positionable in a loading orientation in which the first channel is connected to one or two of the ports to transfer fluid into the first channel and/or the second channel is connected to one or two of the ports to transfer a second fluid into the second channel. The actuator also is positionable into first and second injection orientations in which various ones of the channels and ports are connected for different fluid flow configurations. Each channel has two ends located on a virtual circle whose center coincides with the rotor's axis of rotation. The channels can have a semicircular shape, a semi-oval shape or a U-shape. An analytical system and method that use the inventive valve are also disclosed.

Abstract: A sample transfer device, an analytical system for analyzing a sample, a method for sample transfer and a method for manufacturing the sample transfer device are disclosed. The sample transfer device includes at least one first block and at least one second block, wherein the first block has at least one first port and at least one second port, wherein the second block has at least one third port and at least one fourth port. The sample transfer device also has at least one slider. The slider is located between the first block and the second block and is configured to slide from a first position to a second position and vice versa. Both in the first position and in the second position a first straight channel is formed between the first port and the third port and a second straight channel is formed between the second port and the fourth port.
