    摘要： The present invention relates to a vacuum pumping system (100) comprising a vacuum pump (10) and provided with a soundproofing arrangement (40, 50, 60). The vacuum pumping system of the invention comprises a vacuum pump (10) accommodated in a pump housing and a soundproofing hood (50) surrounding said pump housing and provided with a hood air inlet (52) and a hood air outlet (54). In order to improve dampening of the noise generated by the vacuum pumping system, one or more additional soundproofing shielding element(s) is/are provided between the hood air inlet and the pump housing air inlet and/or between the hood air outlet and the pump housing air outlet, respectively. In a preferred embodiment of the invention, said one or more additional soundproofing shielding element(s) is/are designed as a casing (40) surrounding said pump housing and provided with a casing air inlet (46) and a casing air outlet (48).

    摘要： A quadrupole rod assembly (500) includes a plurality of electrically conductive rods (104), electrically insulating rings (354, 356) coaxially surrounding the rods (104), and clamping systems (472, 474). The rods (104) are arranged about a longitudinal axis (L). The rods (104) and rings (354, 356) have respective surfaces oriented in a transverse plane orthogonal to the longitudinal axis (L), which surfaces interface with respective surfaces of the clamping systems (472, 474) that are also oriented in the transverse plane.

    摘要： An ion transfer device (188; 288; 388; 488; 588; 688; 788; 888; 988) for transferring ions from one chamber to another, reduced-pressure chamber includes an inlet section section (214; 314; 414; 514; 614; 714; 814; 914) and a main capillary section (218; 318; 418; 518; 618; 718; 818; 918). The inlet section has a lumen (222; 322; 422; 522; 622; 722; 822; 922) and the main capillary section has a bore (230; 330; 430; 530; 630; 730; 830; 930) communicating with the lumen. The inside diameter of the lumen is less than that of the bore. The inlet section may be removable from an installation site separately from the main capillary section. The ion transfer device may be utilized, for example, in an atmospheric-pressure interface of a mass spectrometer.

    摘要： A sample management device (100) which comprises a source flow path (102) in which a fluidic sample can flow, a volume flow adjustment unit (104) configured for adjusting a volume flow of the fluidic sample to be branched off from the source flow path (102) at a fluidic coupling point (108), and a fluidic valve (106) fluidically coupled with the source flow path (102) and with the volume flow adjustment unit (104), wherein the fluidic valve (106) is switchable into a branch off state in which the fluidic coupling point (108) is established within the source flow path (102) to branch off an adjustable volume of the fluidic sample from the source flow path (102) via the fluidic coupling point (108) while a flow of the fluidic sample in the source flow path (102) continues.

    摘要： An apparatus and method for generating a mid-infrared region image of a specimen (16) are disclosed. The apparatus includes a mid-infrared region laser (11) that generates a first light beam (18), and a stage (57) adapted to carry a specimen to be scanned. An optical assembly (31) focuses the first light beam to a point on the specimen. A first light detector (13) measures a first intensity of light leaving the point on the specimen. A stage actuator assembly causes the specimen to move relative to the point in two dimensions. A controller (39) forms a mid-infrared region image from the first intensity. The image can be based on reflected or transmitted light. The maximum size of the imaged area is determined by a scanning assembly that moves in a first direction relative to the stage, the stage moving in a direction orthogonal to the first direction.

    摘要： The invention provides a multi-inlet sampling device for an ion source. In general, the sampling device contains at least two sample inlet capillaries and a single outlet capillary that are all fluidically connected. A mass spectrometer ion source and a mass spectrometer system containing the multi-inlet sampling device are also provided. The device is readily removed and installed at ambient pressure without venting the mass spectrometer. Also provided by the invention are methods for simultaneously introducing at least two samples into a mass analyzer.
