Increased sensitivity in proton transfer reaction mass spectrometry by incorporation of a radio frequency ion funnel
Shane Barber, Robert S. Blake, I. R. White, Paul S. Monks, Fraser Reich, Steve Mullock, Andrew Michael Ellis
Izvirni znanstveni članek
Oznake: analytical performance;detection sensitivity;drift tube;dynamic range;ion funnels;proton-transfer;reaction mass spectrometry;
A drift tube capable of simultaneously functioning as an ion funnel is demonstrated in proton transfer reaction mass spectrometry (PTR-MS) for the first time. The ion funnel enables a much higher proportion of ions to exit the drift tube and enter the mass spectrometer than would otherwise be the ca ...

Oznake: volatile organic compounds;breath;mass spectrometry;cystic fibrosis;proton transfer reaction;
The prospects for exploiting proton transfer reaction-time of flight-mass spectrometry (PTR-ToF-MS) in medical diagnostics are illustrated through a series of case studies. Measurements of acetone levels in the breath of 68 healthy people are presented along with a longitudinal study of a single per ...
