Chemical ionization with reactant ion formation at atmospheric pressure in a mass spectrometer


The invention relates to the production of water cluster ions (“hydronium clusters”) at atmospheric pressure for the chemical ionization of analyte molecules. It is proposed that a corona discharge at the taylor cone of an aqueous liquid, preferably pure or slightly acidified pure water, is used instead of corona discharges on metal tips, which have been the usual method up to now.

Gaseous sample injection valve and gaseous sample injection method using same


The present invention relates to a gaseous sample injection valve. The gaseous sample injection valve includes a middle body injecting a fixed amount of a gaseous sample into the vacuum chamber of a mass spectrometer, the middle body being constituted by a gaseous sample injection tube, a gaseous sample discharge tube, a storage part, and a vacuum chamber connection tube; an upper body accommodating a first solenoid coil, a first plunger, and a first packing; and a lower body accommodating a second solenoid coil, a second plunger, and a second packing.

Simultaneous inorganic mass spectrometer and inorganic mass spectrometry


An inorganic mass spectrometer capable of measuring a relevant and large or the full mass spectral range simultaneously may include a suitable ion source (e.g., an icp mass spectrometer with an icp ion source), an ion transfer region, ion optics to separate ions out of a plasma beam, a mattauch-herzog type mass spectrometer with a set of charged particle beam optics to condition the ion beam before an entrance slit, and a solid state multi-channel detector substantially separated from ground potential and separated from the potential of the magnet.. .

Methods for predictive automatic gain control for hybrid mass spectrometers


A method for mass analyzing ions comprising a restricted range mass-to-charge (m/z) ratios comprising performing a survey mass analysis using a mass analyzer to measure a flux of ions having m/z ratios within said restricted range and performing a dependent mass analysis of an optimal quantity of ions having m/z ratios within said restricted range, said optimal quantity collected for a time period determined by the measured ion flux, characterized in that: the time period is determined using a corrected ion flux that accounts for one or more of: (a) imperfect restriction of collected ions to the range of m/z ratios, (b) inclusion of ions within the range of m/z ratios that are undetected by the survey mass analysis, (c) different mass analyzers used for the dependent and survey mass analyses, and (d) different ion pathways used during dependent and the survey mass analyses.. .

Method for automated checking and adjustment of mass spectrometer calibration


A method for automatically checking and adjusting a calibration of a mass spectrometer having a first quadrupole (q1), a fragmentation cell and a mass analyzer comprises: introducing a sample having at least one known chemical entity; decreasing a kinetic energy so as to prevent fragmentation of ions in the fragmentation cell; optionally applying a drag field to the fragmentation cell; ionizing the at least one known chemical entity sample to generate a set of ions; performing a mass scan of the set of ions using q1; transmitting the scanned ions through q1 to and through the fragmentation cell; detecting the scanned and transmitted ions by a detector of the mass analyzer; and comparing the results with expected results. Embodiments may include automatic recalibration or notification of possible errors, need for further data processing or an analysis of system performance..

High-throughput mass-spectrometric characterization of samples


The invention relates to the characterization of samples which are located in their many hundreds up to tens or hundreds of thousands on a sample support plate in a regular pattern, a so-called array, by ionization with matrix-assisted laser desorption and mass spectrometric measurement, for example. The invention proposes that the position of the sample pattern, and thus the position of each sample in the measuring instrument, for example a mass spectrometer, should be determined by measuring at least two finely structured internal position recognition patterns, such as fine crosses.
