Operation of ion mobility spectrometers based on gases pushing the ions over electrical field barriers, preferably in combination with mass spectrometers, and relates to trapped ion mobility spectrometers (TIMS). The ions of a selected range of mobilities are accumulated and scanned by using a long and flat electric field ramp created by additional voltages. By a voltage supplied at the beginning of the flat ramp, the lowest mobility of the mobility range of ions to be collected can be selected. By the difference of the voltages at the beginning and the end, the width of the mobility range is determined. The spatial zoom advantageously can collect considerable more ions of interest than a temporal zoom without severe losses by space charge effects, and more ions can be detected in the mass-mobility map.

method for acquiring fragment ion spectra of substances in complex substance mixtures wherein a trapped ion mobility spectrometer (TIMS) is used as the ion mobility separator separation device. The fragment ion spectra may be used for the identification of high numbers of proteins in complex mixtures, or for a safe quantification of some substances, by their fragment ion mass spectra in a mass spectrometer with up-front substance separator. TIMS with parallel accumulation provides the unique possibility to prolong the ion accumulation duration to find more detectable ion species without decreasing the measuring capacity for fragment ion mass spectra. The high measurement capacity for fragment ion mass spectra permits the repeated measurement of low abundance ion species to improve the quality of the fragment ion spectra.

The invention relates to a low-cost spring steel plate as the sample support on a dimensionally stable and precisely shaped substructure, machined from an aluminum alloy, for example, and using a pattern of embedded magnets so that said plate is removable and that a body is created overall which is suitable for use in robots, for example by giving it the dimensions of a conventional microtitration plate. The planarity of the surface onto which the (organic) samples are applied is provided within the near region by the spring steel plate itself and in the far region over the whole spring steel plate by the substructure. The spring steel plate may be designed for single use in order to satisfy IVD diagnostic regulations also, for example. It can be equipped with identification codes, sample site markings and pre-coatings for different types of analytical tasks, such as MALDI-TOF mass spectrometric analysis.

A method for determining the concentration ratio in a sample of a target peptide to a reference peptide that is chemically identical with the target peptide, but labeled by isotopes, acquires mass spectra of the target and reference peptides. One of a plurality of families of superimposed bell-shaped curves which is a best fit to ion current peak groups of the target and reference peptides in the mass spectra is determined by varying parameters of the families. In each family, each bell-shaped curve has a predetermined height, the curves have fixed distances from each other and the relative curve heights and curve distances in the families are individually calculated from an elemental composition of the peptides and an isotope abundance distribution of elements composing the peptides, taking into account purity of the isotopes. The concentration ratio is then determined from the parameters of the best fit.

A method for performing an X-ray diffraction analysis of a crystal sample (112) using a two-dimensional detector (114) that integrates an X-ray diffraction signal while the position of the sample (112) relative to an X-ray source (102) is changed along a scan direction, such as a rocking scanning curve. The resulting image is compressed along the scan direction, but may be collected very quickly. The capture of both on-axis and off-axis reflections in a single image provides a common spatial frame of reference for comparing the reflections. This may be used in the construction of a reciprocal space map, and is useful for analyzing a sample with multiple crystal layers, such as a crystal substrate with a crystalline film deposited thereupon.

A method for X-ray detection using a charge-integrating X-ray detector (10) including a photodetector array (12) of pixels (14), each of which converts incident radiation into accumulated charge during an X-ray exposure, is provided. The method includes, for each pixel, reading out the accumulated charge from the pixel and determining an X-ray charge value from the read out accumulated charge. If the X- ray charge value is less than a photon counting threshold, the X-ray charge value is replaced with a quantized charge value representative of an estimated photon count and recording the quantized charge value as a recorded charge value. If, however, the X-ray charge is equal to or greater than the photon counting threshold, the X-charge value is recorded as the recorded charge value. The method allows operating a charge-integrating X-ray detector in a mixed photon- counting/analog output mode.

A probehead of an NMR-MAS apparatus includes a sample which has a rotation axis tilted by an angle >0 with respect to the z-axis. The angle can be adjusted about a target angle _(target )by tilting around a tilt axis. The rotation axis has a fixed angle with respect to the probehead, and the NMR-MAS apparatus tilts at least part of the probehead to adjust the angle . The probehead has a support frame with an outer contour K between an upper end and a lower end. For all z between the upper end and the lower end, a cross-section S(z) of the contour K exists parallel to the xy-plane with a width Q(z) in the x-direction. The width Q(z) is smaller at points away from z=0, such that Q(z1)

The TAKE5 project is the next in a chain of thematically connected ENIAC JU KET pilot line projects which are associated with 450mm/300mm development for the 10nm technology node and the ECSEL JU project SeNaTe aiming at the 7nm technology node. The main objective of the TAKE5 project is the demonstration of 5nm patterning in line with the industry needs and the ITRS roadmap in the Advanced Patterning Center at the imec pilot line using innovative design and technology co-optimization, layout and device architecture exploration, and comprising demonstration of a lithographic platform for EUV technology, advanced process and holistic metrology platforms and new materials. A lithography scanner will be developed based on EUV technology to achieve the 5nm module patterning specification. Metrology platforms need to be qualified for 5nm patterning of 1D, 2D and 3D geometries with the appropriate precision and accuracy. For the 5nm technology modules new materials will need to be introduced. Introduction of these new materials brings challenges for all involved deposition processes and the related equipment set. Next to new deposition processes also the interaction of the involved materials with subsequent etch steps will be studied. The project will be dedicated to find the best options for patterning. The project relates to the ECSEL work program topic Process technologies More Moore. It addresses and targets as set out in the MASP at the discovery of new Semiconductor Process, Equipment and Materials solutions for advanced CMOS processes that enable the nano-structuring of electronic devices with 5nm resolution in high-volume manufacturing and fast prototyping. The project touches the core of the continuation of Moores law which has celebrated its 50th anniversary and covers all aspects of 5nm patterning development.
