Voorbeelden van mass spectrometer

• The analysis of products was performed using a gas chromatograph coupled to an infrared detector and a quadrupole mass spectrometer.

• The argon analysis was performed using the isotope dilution procedure on a noble gas mass spectrometer in duplicate.

• The mass spectrometer was used in static multi-collector mode for this study.

• The evolved gases are analysed by a mass spectrometer.

• Individual oligomers produced in heating experiments on urea-amino acid mixtures were analysed using a liquid chromatograph mass spectrometer.

• The diagnostic systems consisted of an electrostatic mass spectrometer and an ion collector.

• The same mass spectrometer is also able to detect negative ions resulting from a proton subtraction.

• The gas generated at each temperature will be analysed by the mass spectrometer.
