The direct separation and analysis of chiral drugs in the complex matrix systems are meaningful and challenging. As the most common broad-spectrum antibiotic, levofloxacin has a strong antibacterial ability, but its enantiomer, dextrofloxacin can cause serious harm to human health. In this work, we reported a rapid on-line extraction/ionization device coupled with Electrospray Mass Spectrometry (ESI-MS)...
A series of diimine ligands (DLs) have been synthesized and evaluated for their non-enzymatic chemiluminescence (CL) enhancement of isoluminol or luminol-containing compounds. Of the DLs, N,N’-bis(m-hydroxylbenzylidene)propylenediamine (DL 10) was found to greatly enhance their CLs approximately 40 folds for isoluminol, 10 folds for luminol and 6 folds for a luminol-containing polymer. The CL enhancement...
