In the present study, LC-QTOF/MS was demonstrated as a suitable method for identifying the degradation products on the electrode surfaces, which allows the deterioration mechanism of the batteries to be traced. In this study, we considered the degradation of LIBs by cycling under certain conditions, which is a type of battery degradation mode.
Within this market, therapeutic monoclonal antibodies (mAbs) are the dominant product class. With the patent expirations, biosimilars and, perhaps more relevant, biobetters, are in fast development. Thus, a comprehensive characterization at the molecular level of antibodies heterogeneity such as 24 Jan 2020 Content determination of hydroxysafflor yellow A in Tibetan Medicine Shisanwei Honghua Pills by LC-MS/MS.

The dietary supplements with claimed antioxidant activity constitute a substantial part of the dietary supplement market. In this study, we performed the LC-QTOF-MS analysis and investigated the activity profiles of popular antioxidant dietary supplements from different chemical groups in terms of quality control. The commonly used antioxidant tests and statistical analysis revealed that
Standard Metabolomics analysis by GC-TOF-MS and LC-QTOF-MS Details Last Updated: Friday, 04 September 2020 13:31 The standard metabolomics analysis at SMC is performed using both GC-MS and LC-MS (positive and negative electrospray ionisation). 2019-06-01

LC/MS is a hyphenated technique, which combines the separating power of High Performance Liquid Chromatography (HPLC), with the detection power of mass spectrometry. Mass Spectrometry is a wide-ranging analytical technique, which involves the production and subsequent separation and identification of charged species.
