    Abstract: A sample injector for an analytical device includes a needle seat configured to receive a needle for injecting a sample into an injector path. The needle seat is mounted in a floating manner so that the orientation of the needle seat is aligned automatically with respect to the orientation of the approaching needle. The sample injector may be provided in an analytical device such as a chromatographic device.

    Abstract: A sample handling device for handling a sample container, in particular for an analysis device for analyzing a fluidic sample in the sample container, includes: i) a push-push mechanism for fixing and releasing the sample container; and ii) a coupling region for releasably coupling to a sample moving device. The sample handling device is a passive device which is adapted to perform the fixing and the releasing free of a drive, in particular a motor. Furthermore, a related sample handling arrangement, an analysis device, and a method are described.

    Abstract: A sample injector is provided for a chromatography system that includes a mobile phase drive and a separation unit. The mobile phase drive is configured for driving a mobile phase through the separation unit, and the separation unit is configured for chromatographically separating compounds of a sample fluid in the mobile phase. The sample injector is configured for injecting the sample fluid into the mobile phase and comprises a needle and a handling unit configured for positioning the needle. Operating the sample injector includes providing a receptacle that includes a filtration unit configured for filtering a sample fluid comprised within the receptacle, moving the filtration unit within the receptacle in order to filter at least a portion of the sample fluid contained in the receptacle, operating the handling unit to position the needle into the receptacle, and aspirating a volume of the filtered sample fluid.

    Abstract: A sample separation apparatus includes a fluid drive arrangement having a first fluid drive unit and a second fluid drive unit for driving a mobile phase along a flow path to a sample separation unit, a sample accommodation volume configured to accommodate the fluidic sample and to be selectively fluidically coupleable with the flow path or fluidically decoupleable from the flow path, and a control unit configured to control respective operations of the fluid drive units, and to control a fluidically decoupling of the second fluid drive unit from the flow path in a decoupled operation mode of the sample separation apparatus. The control unit is further configured to control, in the decoupled operation mode, the decoupled second fluid drive unit for fluidically coupling to the sample accommodation volume, and intaking sample into the sample accommodation volume.

    Abstract: A valve may be utilized in a high-performance chromatography system for separating components of a sample liquid introduced into a mobile phase. The valve has a first valve element and a second valve element. By a movement of one valve element relative to the other, a first effective surface of the first valve element is brought into connection with a second effective surface of the second valve element, and a flow path may be produced or suppressed. The second valve element has an elastic region to compensate for an axial angle between the first valve element and the second valve element, such that the first effective surface and the second effective surface may be oriented parallel to each other. This may favorably influence a fluidic leak tightness and/or longevity of the valve.

    Abstract: A sample injector for a chromatography system is configured for injecting a sample fluid into a mobile phase, and includes a needle and a conduit. The needle is configured for aspirating the sample fluid and includes a needle tip, a needle channel through the needle for guiding the aspirated sample fluid, and a needle opening at the needle tip into which the needle channel opens. The conduit is configured for fluidically coupling with the needle and includes a conduit tip, and a conduit channel through the conduit for guiding fluid and having a conduit opening at the conduit tip. The conduit tip and the needle tip are configured to be pressed against each other for fluidically coupling the conduit channel with the needle channel, with at least a portion of the conduit tip penetrating into the needle opening for providing the fluidic coupling between the conduit and needle channels.
