Determination of carbapenems in water samples by UHPLC–MS/MS

Journal of Separation Science, 2020
AbstractA rapid and reliable method for the detection of five carbapenems (biapenem, imipenem, doripenem, meropenem, and faropenem) in water was developed and validated. After acidification of water samples with acetic acid, carbapenems were isolated using a Bond Elut PPL cartridge.

Integrative metabolic profile of myelodysplastic syndrome based on UHPLC–MS

Biomedical Chromatography, 2021
AbstractMyelodysplastic syndrome (MDS) is a neoplastic disease originating from hematopoietic stem cells. Currently, hematopoietic stem cell transplantation (HSCT) is the most effective cure, although lenalidomide, azacytidine, and decitabine have been applied to relieve symptoms of MDS.

Quantitative Analysis of Bile Acid with UHPLC-MS/MS

2020
Bile acids are important end products of cholesterol metabolism, having been shown to serve as signaling molecules and intermediates between the host and the gut microbiota. Here we describe a robust and accurate method using ultrahigh-pressure liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) for the quantification of bile ...

Profiling of iridoid glycosides in Vaccinium species by UHPLC-MS

Food Research International, 2017
The iridoid profile of four Vaccinium species was investigated using UHPLC-MS to obtain further information about this group of species for phytochemical characterization. Fruits of bog bilberry (Vaccinium uliginosum L.) showed 14 different iridoid glycosides with a total amount of 20mg/kg fresh weight (FW), whereas bilberry (Vaccinium myrtillus L ...

Profiling of illicit fentanyl using UHPLC–MS/MS

Forensic Science International, 2012
Methodology is presented for the profiling of fentanyl in seized drugs using ultra high performance liquid chromatography in combination with tandem mass spectrometry (UHPLC-MS/MS). Target analysis was performed for 40 fentanyl processing impurities, several of which are markers for a specific synthetic route (Siegfried or Janssen).
