MALDI-TOF MASS SPECTROMETERS WITH DELAY TIME VARIATIONS AND RELATED METHODS

MALDI-TOF MS systems have solid state lasers and successive and varied delay times between ionization and acceleration (e.g. extraction) to change focus masses during a single sample signal acquisition without requiring tuning of the MS by a user. The (successive) different delay times can change by...

Zusammenfassung:MALDI-TOF MS systems have solid state lasers and successive and varied delay times between ionization and acceleration (e.g. extraction) to change focus masses during a single sample signal acquisition without requiring tuning of the MS by a user. The (successive) different delay times can change by 1 ns to about 500 ns, and can be in a range that is between 1-2500 nanoseconds. L'invention concerne des systèmes de spectromètre de masse (MS) MALDI-TOF qui comprennent des lasers à solide et des temps de retard successifs et variables entre ionisation et accélération (par exemple extraction) pour changer les masses focalisées pendant l'acquisition d'un seul signal d'échantillon sans requérir un réglage du MS par un utilisateur. Les temps de retard différents (successifs) peuvent varier par pas de 1 ns à environ 500 ns, et peuvent être inclus dans une plage qui est comprise entre 1 et 2500 nanosecondes.
