    摘要： An attachment device for releasably attaching a fluid line to a fluid inlet or outlet is disclosed. The device comprises an attachment member for releasably engaging a fluid inlet or outlet, and an elastic member coupled to the attachment member. The attachment device is attachable to a fluid line such that the attachment member is moveable relative to the fluid line and such that movement of the attachment member relative to the fluid line causes elastic deformation of the elastic member.

    摘要： A mass spectrometer is disclosed comprising a first component, an annular vacuum chamber seal and a second component. The first component has a groove. The annular vacuum chamber seal comprises a main body portion and one or more blade or rib portions which protrude from the main body portion. The main body portion is located in the groove and the one or more blade or rib portions protrude above or beyond a surface of the first component. The second component is slid, in use, along the surface of the first component thereby deforming the one or more blade or rib portions so that the one or more blade or rib portions form a radial, diametric or piston seal between the first and second components.

    摘要： An apparatus for connecting an ionization probe assembly to a mass and/or ion mobility spectrometer is disclosed. The apparatus comprises: an attachment member for releasably attaching a probe assembly to the apparatus; a cap for enclosing the attachment member; wherein the apparatus is operable to deliver a voltage to a probe assembly only when the cap is arranged to enclose the attachment member; and wherein the cap is configurable to enclose the attachment member when a probe assembly is attached to the apparatus.

    摘要： A mass spectrometer is disclosed comprising an atmospheric pressure interface comprising a gas cone 6 having an inlet aperture, wherein the gas cone 6 has a first longitudinal axis arranged along an x-axis and an Electrospray ion source comprising a first capillary tube 2 having an outlet and having a second longitudinal axis and a second capillary tube 3 which surrounds the first capillary tube 2. The mass spectrometer further comprises a desolvation gas supply tube and a first device arranged and adapted to supply an analyte liquid via the first capillary tube 2 so that the liquid exits the outlet of the first capillary tube 2 at a flow rate >200 μL/min. The mass spectrometer further comprises a second device arranged and adapted to supply a nebuliser gas via the second capillary tube 3 at a flow rate in the range 80-150 L/hr, wherein an outlet of the first capillary tube 2 is arranged at a distance x mm along the x-axis as measured from the centre of the gas cone inlet aperture, a distance y mm along a y-axis as measured from the centre of the gas cone inlet aperture and a distance z mm along a z-axis as measured from the centre of the gas cone inlet aperture. The x-axis, the y-axis and the z-axis are mutually orthogonal. The desolvation gas supply tube surrounds the second capillary tube 3 and the mass spectrometer further comprises a third device arranged and adapted to supply a desolvation gas via the desolvation gas supply tube at a flow rate in the range 400-1200 L/hr, a heater 4 arranged and adapted to heat the desolvation gas to a temperature ≥100° C. and a fourth device arranged and adapted to supply a cone gas to the gas cone 6 at a flow rate in the range 40-80 L/hr and wherein x is in the range 2.0-5.0 mm and wherein the ratio z/x is in the range 1-5:1.
