Title (EN) FIELDS FOR MULTI-REFLECTING TOF MS
(FR) CHAMPS SERVANT À DES SM TOF À RÉFLEXION MULTIPLE
Abstract:
(EN) A multi-reflecting time-of-flight mass spectrometer MR TOF with an orthogonal accelerator (40) is improved with at least one deflector (30) and/or (30R) in combination with at least one wedge field (46) for denser folding of ion rays (73). Systematic mechanical misalignments (72) of ion mirrors (71) may be compensated by electrical tuning of the instrument, as shown by resolution improvements between simulated peaks for non compensated case (74) and compensated one (75), and/or by an electronically controlled global electrostatic wedge/arc field within ion mirror (71).
(FR) La présente invention concerne un spectromètre de masse à temps de vol à réflexion multiple (MR TOF) pourvu d'un accélérateur orthogonal (40), qui est amélioré au moyen d'au moins un déflecteur (30) et/ou (30R) en combinaison avec au moins un champ de coin (46) de façon à courber de manière plus dense les rayons ioniques (73). Des désalignements mécaniques systématiques (72) de miroirs ioniques (71) peuvent être compensés par accord électrique de l'instrument, tel qu'illustré par des améliorations de résolution entre des pics simulés en ce concerne un cas non compensé (74) et un cas compensé (75), et/ou par un champ d'arc/de coin électrostatique global à commande électronique dans un miroir ionique (71).
