IT data provided a better understanding of the fragmentation pathways using MS n experiments. With respect to analytical performance, all four mass analyzers showed a good linearity ( R 2 > 0.97) and repeatability (CV < 20%). Detection limits (LoDs) (S/N = 3) were the lowest on triple...
Our team at Polymer Solutions Incorporated (PSI) decided to make a major investment in our analytical capabilities by acquiring and installing a liquid chromatography-mass spectrometry (LC-MS) system, specifically a Waters Xevo G2-XS QTof. There are many different types of LC-MS instruments ...
Analytical or laboratory applications may include gas chromatography (GC, GC-MS, LC-MS), spectrometry (ICP, ICP-MS, Flame A.A., GFAA, NMR), specialty analysis techniques (thermal and elemental analysis, total organic carbon analyzers), as well as sample or materials processing. Some ...
All the samples were filtered via a 0.2-μm cellulose nitrate membrane which showed no adsorption of tetracycline (Li et al.2009), kept in dark at 4 °C, and analyzed directly via Acquity™ ultraperformance liquid chromatography–tandem mass spectrometry (UPLC-MS/MS, Waters) within 24 h. ...
