Abstract: The invention relates to a method for the mass spectrometry examination of at least one analyte, wherein an analyte to be examined is photoionized and the mass of the ions produced is determined in a mass spectrometer. The analyte to be examined is ionized at normal atmospheric ambient pressure by means of laser light using multiphoton ionization, especially resonant multiphoton ionization. The invention also relates to a device which comprises an ionization chamber in which an analyte to be examined is ionized at normal atmospheric ambient pressure using resonant multiphoton ionization and is transferred into a mass spectrometer. Said device can be used as an interface between a device for the chromatographic or electrophoretic separation of analytes and a mass spectrometer.

Abstract: An apparatus for cutting photoresist webs into photoresist sheets of defined size and exact, fold-free lamination of the photoresist sheets with flexible and rigid bases, for example blank circuit boards, consisting of a copper-plated base, is integrated into a movable assembly of a laminator so that cutting and lamination are effected without interrupting the lamination process.
