  • Publication number: 20090284740
    Abstract: The invention relates to spectrometer optics with a beam path from a beam source to a number of electro-optical sensors without spatial resolution, the beam path comprising an entry slot, a dispersive element, and a number of exit slots arranged on a focal curve, wherein furthermore: a first actuator for changing the angle of incidence ? between the beam from the entry slot to the dispersive element and from the normal to the dispersive element; a number of second actuators for moving the exit slots tangentially with respect to the focal curve or in a peripheral direction along the focal curve and a controller which is adapted to control the first actuator and the second actuators to carry out a calibration is provided.

  • Patent number: 7511278
    Abstract: An apparatus for detecting particles, comprising a plurality of electrically conductive structures disposed on a support element. The structures are electrically insulated from one another and each structure can be electrically connected to an electronic read-out device. The structures receive a beam of particles in a direction forming an angle of incidence with the support element. A trough is disposed between each two successive structures as viewed in the beam direction. And at least partial overlap exists between each two successive structures. The apparatus can be disposed in the focal plane of a mass spectrometer.

  • Publication number: 20090014635
    Abstract: The present invention relates to a method for correcting spectral interference in a spectrum which is determined using an inductively coupled plasma spectrometer (ICP) for analysing element contents of a liquid or gaseous sample, comprising the following steps: recording the spectrum of a matrix solution containing all spectrally interfering components, which are also contained in the sample, in a first concentration; recording the spectrum of the matrix solution in at least one dilution of the first concentration; regressing the signal intensities obtained in steps a. and b. against the concentration for a number of wavelength positions; calibrating the spectrometer, background correction using the values determined from the regression in step c. and determining the calibration function c=f(I); recording the sample spectrum using at least one analyte which is contained therein; determining the concentration of the spectrally interfering components in the sample using the results obtained in step c.

  • Patent number: 7227636
    Abstract: An optical emission spectrometer for analysis, identification or identity testing of metallic materials, and a method for optical emission analysis of metallic materials with a spectrometer, wherein the spectrometer has at least one arc or spark generator for producing a discharge between an electrode and a workpiece in a spark stand chamber of the generator. A cleansing apparatus for air about the discharge includes a pump for feeding air into the spark stand chamber, and a container through which air can flow. The container contains an alkaline metal or alkaline earth metal hydroxide or another substance that binds CO2 present in air.

  • Patent number: 5731872
    Abstract: The invention relates to a device for emission spectrum analysis with an analysis plasma containing the analysis sample and a spectrometer suitable for emission measurements, in which there is a plasma manipulator (4) with a cooled diaphragm (8) concentric with the axis (7) and perpendicular to the direction of expansion of the plasma with a free diameter smaller than that of the plasma which allows only the central part (6) or only the optical part of the analysis plasma to pass and masks off the remaining region, and an observation device (3) for the radiation emission of the volume of plasma allowed through.
