Quadrupole time-of-flight mass spectrometry (Q-TOF-MS) has gained considerable attention over the last decade as an analytical technique that is capable of meeting the challenges of a rapidly changing drug landscape.

In this study, eighty-four (84) phenolic compounds were screened and confirmed through LC-MS/MS by comparing their masses and fragmentation pattern with published libraries. The results of this study validate the use of these herbs as bioactives and …

A liquid chromatography–quadrupole time-of-flight (Q-TOF) mass spectrometric method was developed for early-stage research on adalimumab in rats.

Gas chromatography/ quadrupole time-of-flight mass spectrometry (GC/Q-TOF) offers high mass resolution and accurate mass data with the ability to perform structure elucidation and confirmation via MS/MS processes for a myriad of analytes in …

QToF is capable of measuring mass to the 4th decimal place and is frequently used for pharmaceutical and toxicological analysis as a screening method for drug analogues. [24] Identification is done by collection of the mass spectrum and comparison to tandem mass spectrum libraries. [25]

Quadrupole Time-Of-Flight (QTOF) mass spectrometer is used to collect MS or MS/MS data. Qualitative Analysis version .07 or higher will be used for this SOP and this software is installed on the QTOF data

QTOF Data Acquisition – What to Know Before You Hit “Go” Society of Forensic Toxicologists (SOFT) Annual Meeting – Monday October 30, 2023 Workshop 3: QTOF 101: A Guide to Successful Development and Validation Alex J. Krotulski, Ph.D. – Center for Forensic Science Research and Education (CFSRE)

Oct 1, 2023 · Untargeted analysis requires high-resolution accurate mass instrumentation such as a quadrupole time of flight (QTOF) mass spectrometer. Such instrumentation is more costly than instrumentation options with a lower resolving power.
