20090084949 | EVALUATION OF SPECTRA IN OSCILLATION MASS SPECTROMETERS - The invention relates to mass spectrometers in which ion clouds are stored in two spatial directions by radial forces while oscillating largely harmonically at a mass-specific frequency in a third spatial direction perpendicular to the other two, in a potential minimum, the shape of which is as close to a parabola as possible. Analysis of the oscillation frequencies of these ion clouds, preferably by a Fourier analysis, leads via a frequency spectrum to a mass spectrum. The frequency spectrum is analyzed to identify false signals in the frequency spectrum as harmonics and eliminating them where necessary. | 04-02-2009 |
20090294647 | MEASURING THE MOBILITY OF MASS SELECTED IONS - In an ion mobility spectrometer (IMS) coupled to a mass spectrometer (MS), the ion current from a suitable ion source is modulated with an analog modulation having a smooth modulation function, whose instantaneous frequency varies with time over a wide frequency range. The modulated ion current is continuously fed through a mobility drift region into the mass spectrometer, where the temporally varying ion current profile of at least one ion species is measured. The mobility spectrum of the ion species is then generated by correlating its ion current time profile with the modulation function. | 12-03-2009 |
20090294651 | EVALUATION OF FREQUENCY MASS SPECTRA - The invention relates to the evaluation of mass spectra from mass spectrometers in which ions are excited to mass-specific oscillating or orbiting motions, and the ion motion is recorded as a time signal. The invention provides methods to detect parameter drift that occurs during the recording of a time signal in such a “frequency mass spectrometer” by analyzing the instantaneous frequency or the phase spectrum of a frequency component, and provides a method to correct for influence of the frequency drift on the mass spectrum correspondingly. In one embodiment a Fourier transformation converts a measured time signal into a frequency spectrum and examines the phase spectrum of a frequency component to establish whether this phase spectrum deviates from the phase spectrum of a harmonic time signal. The phase spectrum of a harmonic time signal is either linear or constant. In another embodiment the time domain signal is processed using a Short Time Fourier Transformation function to determine an instantaneous frequency, which can be used to correct the parameter drift, yielding a corrected time signal. From the corrected time signal a mass spectrum with better mass resolution can be derived, as can be seen from corrected mass signal profile compared with uncorrected mass signal profile. | 12-03-2009 |
20110284738 | CONFINING POSITIVE AND NEGATIVE IONS IN A LINEAR RF ION TRAP - In a linear ion trap, ions with two polarities are confined radially via an RF potential between the rods comprising the trap. Axially, ions of at least one polarity are confined via DC potentials applied to the elements of the trap or electrodes at the ends of the trap whereas ions of the other polarity are axially confined by a combination of pseudopotentials and/or DC potentials. | 11-24-2011 |
20110284741 | MIXED RADIO FREQUENCY MULTIPOLE ROD SYSTEM AS ION REACTOR - The invention relates to a linear multipole ion storage device which is suitable for reactions between positive and negative ions, and for fragmentation reactions by electron transfer dissociation (ETD) in particular. The invention uses a linear RF ion trap with at least three pairs of rods with a new type of electronic power supply. The two phases of a first RF voltage are applied to the pole rods alternately around the circumference and confine positive as well as negative ions in the radial direction. A second RF voltage is either applied single-phase to some of the pole rods, but not to all of them, or two-phase to unequal numbers of pole rods so that the axis potential oscillates with the frequency of this second RF voltage and generates a pseudopotential barrier which acts axially on ions of both polarities at the ends of the ion storage device. In the interior, the second RF produces a complex superposition field resulting in an increased fragmentation yield for ETD. | 11-24-2011 |
20130095511 | MASS SPECTROMETRIC MEASUREMENT OF B-LACTAMASE RESISTANCES - The invention relates to the determination of resistances of microorganisms which produce β-lactamases, in particular “extended spectrum β-lactamases” (ESBL). The invention provides a method whereby the microbial resistance can be measured very simply and quickly by means of the catalytic effect of the microbially produced β-lactamases on β-lactam antibiotics, which consists in a hydrolytic cleavage of the β-lactam ring. The method determines the resistance of the bacteria a few hours after a suitable substrate, either a β-lactam antibiotic or a customized β-lactam derivative, has been added to a suspension of the microbes, by direct mass spectrometric measurement of the substrate breakdown caused by the β-lactamases. | 04-18-2013 |
