Studies of UHPLC-MS performance and application to rapid sensitive and robust drug analysis
This thesis comprises studies of ultra high performance liquid chromatography (UHPLC) performance with a particular focus on the application of liquid chromatography-mass spectrometry (LC-MS) for the analysis of basic drugs. UHPLC-MS technologies are investigated to facilitate fast, sensitive and …

Adsorption of Organic Pollutants onto Microplastics
… of EtP and BP-3 onto PE MPs was analyzed using ultra-high performance liquid chromatography (UHPLC). The UHPLC parameters and figures of merit for EtP and BP-3 were established. The adsorption experiments used size of MPs, weathering of MPs, and time as the experimental variables. Pristine small …

Diel patterns of insect herbivory and plant secondary metabolites in understory shrubs on Barro Colorado Island
… species during daytime and nighttime hours using ultra high-performance liquid chromatography (UHPLC), electrospray ionization and molecular fragmentation, and tandem mass spectrometry (MS/MS). Network analyses show that plant secondary metabolites varied greatly in their presence in leaves over …
