A method for improving the signal intensity of precursor ionsconstrained in a carrier gas in a selected ion flow mass spectrometry (SIFT-MS) instrument, involving applying electrical potential to aflow tube to lower the diffusive loss of ions within the tube.

A manufacturing method for an analytical sample by secondary ion mass spectrometry, involving separating a thin film and thin-film stack body from the substrate.

A mass spectrometry sample stand for analyzing micro samples, comprising a crystalline substance with reverse perovskite structure provided between a base material and an analysis target object. Since the reverse perovskite structure has electrical conductivity as the metal is located in the surroundings, the thermal conductivity is also good and the analysis target object can be ionized efficiently. Hence high spatial resolution can be obtained, even if high energy is applied and temperature rises.

A mass spectrometer for analyzing a protein sample that selectsthe ionic species that are dissociated out of ions generated by the ionization of sample using valence of the ion, determined from mass spectrum data without interference peak.

An inductively-coupled-plasma-source-mass-spectrometry apparatus that supplies additional gas to the intermediate position of alow-vacuum side stage and reduces partial pressure of hydrogengas in the high-vacuum chamber. The rapid increase of partialpressure of hydrogen gas can be prevented and durability of theturbo molecular pump can be increased, allowing the analysisprocess to be performed continuously and stably.

A mass spectrometry system for analyzing metal species within a cell or tissue, with an integrated ionization source with an electrospray ionization source that generates a potential difference across a capillary tube and mass spectrometer interface.

A tandem mass spectrometer with an electrode system positioned between mass analyzers to selectively deflect ions from an ion path for detection.

An electrospray ionization system for liquid chromatography mass spectroscopy with a valve coupled to the inlet of a specific nozzle for selectively nebulizing one of a secondary and calibration liquid. Less expensive and allows for easier optimization of the secondary sprayer, and provides an effective way of introducing a secondary stream of liquid droplets into primary stream of electrosprayed droplets toreference correct time-of-flight mass spectra.

A silica particle useful as matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF-MS) matrix materialfor the adsorption of polar organic compounds (e.g., dioxins, furans, steroids or sterols) and for partial desorption of adsorbed compounds.

A method of detecting lipid-antigen of microorganisms for diagnosing diseases associated with Mycoplasma infections (e.g., asthma),involving analyzing the sample by mass spectrometry and detectingthe spectrum peak specific to lipid antigen.

A new substrate compound for mass spectrometric analysis of enzymes (e.g., alpha-galactosidase A); eliminates the need of detergents, user-unfriendly solvents (e.g., chloroform), and liquid-liquid and solid phase extraction steps. The process is also less time consuming than prior art processes.
