A new method of alpha ray measurement using a Quadrupole Mass Spectrometer
We propose a new method of alpha(α)-ray measurement that detects helium atoms with a Quadrupole Mass Spectrometer(QMS). A demonstration is undertaken with a plastic-covered 241Am α-emitting source to detect α-rays stopped in the capsule. We successfully detect helium atoms that diffuse out of the capsule by accumulating them for one to 20 hours in a closed chamber. The detected amount is found ...
متن کاملA quadrupole mass spectrometer for resolution of low mass isotopes.
The qualitative and quantitative identification of low mass isotopes in the mass range 1-6 u poses certain difficulties when attempting to achieve the required resolution with an instrument suitable for deployment within a process environment. Certain adjacent species present in the process sample (HT and D(2)) require a resolution greater than 930 to achieve an accurate measurement. We demonst...
متن کاملMS1-Based Quantification Optimization on DIA Methods on a Quadrupole-Orbitrap Mass Spectrometer
The performance of DIA methods was influenced by the number of DIA windows, the scan resolution, the gradient length and the sampling of the chromatographic peaks. Additionally, the MS1 scan of the DIA method had an important influence on the performance. To optimize quantification on MS1, we evaluated the following conditions. We established a comprehensive spectral library by measuring tripli...
متن کاملMeasurement of dissolved neon by isotope dilution using a quadrupole mass spectrometer
We describe an analytical method with improved precision for measuring the concentration of neon dissolved in water. Measurements were calibrated by isotope dilution, with addition of a 22Ne spike directly to the evacuated sample flask prior to water collection. The use of glass flasks for water sampling, with flushing of air from the system by CO2, greatly reduced the chance of contamination. ...
متن کاملA microelectromechanical systems-enabled, miniature triple quadrupole mass spectrometer.
Miniaturized mass spectrometers are becoming increasingly capable, enabling the development of many novel field and laboratory applications. However, to date, triple quadrupole tandem mass spectrometers, the workhorses of quantitative analysis, have not been significantly reduced in size. Here, the basis of a field-deployable triple quadrupole is described. The key development is a highly minia...
