However, such a spectrum may be expected as a forbidden transition made possible by the change of quadrupole moment during the vibration 1. The predicted intensity of this spectrum is so low that ...

Abstract: New multistage self-aligned quadrupole correction-lens systems are proposed for correcting the spherical aberration of a rotationally symmetrical lens in a probe-forming system such as ...

Thermo Scientific TSQ Vantage triple stage quadrupole mass spectrometer delivers the highest sensitivity with the lowest noise for the quantitative analysis of small molecules, peptides ...
