assess the analytical limits of detection (LODs) expressed as S/N ratio 53, samples of blank hair were spiked with a mixture of JWH-018, JWH-122, JWH-200, JWH-210, JWH-250, JWH-073, JWH-081 and AM-694 to achieve decreasing individual … The principal component analysis of the LC-QTOF/MS data showed a clear discrimination between both species, using the first two principal components. The key compounds responsible for the discrimination were tentatively identified as sucrose and glycosylated flavonoids by comparison with spectral data bases and previous studies.

The Q-TOF-MS is a ' hybrid' instrument combining quadrupole technologies with a time-of-flight mass   Flight Tandem Mass Spectrometer (LC-QTOF-MS/MS) training 5 Jul 2018 The topic of this training is basic principle of LC-MS, equipment operation,  12 Dec 2014 In principle, QTOF offers increased specificity over TOF if MS-MS it was not possible for each vendor to utilize similar LC and MS methods.

source, and its history (and principles) are well described in. several recent reviews. 3–5 The configuration can be regarded. In this study, metabolites were identified in 13 post-mortem urine samples using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). Samples were analyzed with and without enzymatic hydrolysis, and seven potential metabolites were synthesized in-house to provide the identity of major metabolites. Qualitative tandem liquid chromatography quadrupole time of flight mass spectrometry (LC-QTOF-MS/MS) was utilized to identify compounds in the extract.
