A double laser pulse muluphoton tontzatton technique is presented III conJunction \rlth .I simple tlmcai-fhgbt mass spcctromctcr. The second laser pulse LS used to modrfy the spectrum of the 1011 fr.r_emcnts produced by the iiist laser pub. The ekpetimental data are taken to support the mcchantsm of succcss~ve ladder swttchmg for multiphoton tontzJtton m-5 spectrometry.

Modulated resonant excitation leading to collisionally induced dissociation (CID) of isolated molecular ions of di-ortho-, mono-ortho-and non-ortho-substituted tetrachlorobiphenyl (PCB) compounds was accomplished in a quadrupole ion trap. While the ion trap was irradiated with a supplementary a.c. s
The purpose of this study was to design a quadrupole secondary ion mass spectrometer for simultaneous detection of both positive and negative ions of different mass. An original setup based on a quadrupole electrostatic deflector configuration that allows energy and spatial separation of all types o
A searchable library of MS/MS spectra obtained using a quadrupole ion trap mass spectrometer and electrospray or atmospheric pressure chemical ionization is presented. The application of wideband excitation (activation) and normalized collision energy leads to highly reproducible mass spectra which
