The ion source settings were: nebulizer pressure 2 bars, drying gas flow 8 L/min, dry gas temperature 200 °C, and capillary voltage 4000 V. The price difference between Exactive+ and QExactive+ is around $10K, which is less then 5% of the instrument price. per sample. 1 polarity. 200.00. 150.00. Screening & identification for accurate-mass.

The ESI source is the JetStream source. The instrument is capable of MS and MS/MS and it is using MassHunter software for data acquisition and processing. LC pumps can handle up to 8000 psi. Mass Accuracy of better than Abstract Background Isodon lophanthoides, I. lophanthoides var. graciliflorus and I. serra are the three botanical sources of Xihuangcao, which are often used indiscriminately in herbal products.

The aim of this study was to develop a rapid and accurate analytical method to identify the three different botanical sources of Xihuangcao by combining UPLC-ESI-QTOF-MS with chemometrics analysis Brachychiton acerifolius, or Sterculia acerifolia as formerly known, is a member of a genus reported for a myriad of bioactive compounds. Metabolome analysis of B. acerifolius – leaves, flowers and seeds – and quantification of its major compounds are demonstrated in this study. Metabolites were analysed via UPLC-PDA-qTOF-( ± ) ESI-MS and UPLC/ITMS, with a total of 56 metabolites What does QTOF-MS stand for?

Enkla databaser är helt isolerade databaser som har optimerats för arbetsbelastningar när prestandakraven är relativt förutsägbara. The QTOF-MS instrument was operated with an electrospray ion source ESI+ Agilent Jet Stream Technology in positive ionization mode, a quadrupole for isolation of precursor ions with a mass window of 1.3 or 4 m/z in MS-MS mode, a linear hexapole collision cell with nitrogen as collision gas at 0–40 eV collision energy, a TOF-MS with accuracy <3 ppm, mass resolution of 5,000–10,000 (100 The UPLC-QTOF-MS/MS information of the annotated CQA, pCoQA, and FQA from Momordica plants extracts. The diagnostic ions (Q 1 and Q 2 ) used for isomers differentiation are also shown and they were ubiquitous across all the molecules detected. To speed things up I thought I acquire an MS profile on an LC-QTOF to check the presence of some of the parent ions I targeted on the QQQ and yes, I could find some of them but obviously had no idea about the fragmentation, so the next step was to do targeted MSMS run on the LC-QTOF to check what transitions can be detected for these parent ions.
