Q-TOF-MS is an analytical technique that advantageously combines the benefits of two different mass analysers. Utilising the high compound fragmentation efficiency of quadrupole technology in combination with the rapid analysis speed and high mass resolution capability of time-of-flight, a unique ‘hybrid’ analyser was introduced. 1 … WebbOs mais comuns incluem dois ou mais dos seguintes analisadores: Quadrupolos, TOF (time of flight), ressonância ciclotrônica de íons ou orbitrap. Estes são nomeados instrumentos híbridos. O objetivo de um instrumento híbrido é combinar os pontos fortes de cada analisador, evitando a combinação de suas fraquezas. mexiletine product information

WebbIn terms of detection, a TOF-MS was employed because of the ability of this analyzer to obtain more complete spectral information in contrast to the MRM mode normally used in QqQ-MS. This inherent TOF-MS property, in combination with its high sensitivity, allowed identifying the unwanted compounds more easily.
