We developed a LC‐QTOF/MS method for the quantification of 71 metabolites in urine covering all disorders classically identified through GC‐MS analysis of organic acids. This targeted analyses is aimed at finding most organic acidurias in a fast manner, with the limitation that some IEM classically detected in GC‐MS analysis, such as glycerol kinase deficiency, are not detected.

To answer this question, we compared MS/MS spectra obtained on a Bruker QTof CID and a Thermo Q‐Exactive Focus Orbitrap HCD instrument as a function of collision energy using the similarity index. We developed a LC‐QTOF/MS method for the quantification of 71 metabolites in urine covering all disorders classically identified through GC‐MS analysis of organic acids. This targeted analyses is aimed at finding most organic acidurias in a fast manner, with the limitation that some IEM classically detected in GC‐MS analysis, such as glycerol kinase deficiency, are not detected. Waters Xevo QTof MS is currently shipping worldwide.

I learned that in the case of LC / MS qTOF I would have to use radiolabeled standards for routine analysis. Are they much less available than normal HPLC

General Requirements: The applicant is expected to  GC-ECD, GC/GC-MS/MS-ion trap med PFC, SQ GCGC-MS, SQ GC-MS, SQ-GCMS-EAD (HES), 3 GC-FID, LC-QTOF, LC-RID, LC-DAD, LC-ICPMS, ICP-OES.

Quadrupole time-of-flight (Q-TOF) mass spectrometer (MS) uses a hybrid of technologies. Ions generated at the ion source are first focused into a ‘beam’ and transmitted through the quadrupole, using the proven technologies of the triple-quadrupole mass spectrometers. Quadrupole Time-of-Flight (Q-TOF) MS. By switching the last quadrupole mass analyzer in a TQ MS to a TOF mass analyzer, we will get the Q-TOF hybrid MS (Figure 24). With the inclusion of a TOF, this hybrid system provides excellent dynamic range, high mass resolution and mass accuracy.

Liquid chromatography–mass spectrometry is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography with the mass analysis capabilities of mass spectrometry. Coupled chromatography - MS systems are popular in chemical analysis because the individual capabilities of each technique are enhanced synergistically. While liquid chromatography separates mixtures with multiple components, mass spectrometry provides structural identity
