✦ Synopsis

Several phenolic compounds found in olive mill wastewater were quantitatively and qualitatively analyzed on an uncoated fused-silica capillary electrophoresis column (67 cm  75 mm i.d.) using 30 mM aqueous ammonium acetate buffer/methanol (90:10) and negative electrospray mass spectrometry detection. Quantitative analysis, with p-chlorophenol as the internal standard, was carried out by single ion monitoring Limits of detection ranged from 1 pg for 4-hydroxybenzaldehyde and protocatechuic acid to 386 pg for vanillic acid.

Capillary electrophoresis (CE) coupled to electrospray mass spectrometry via sheathless interfacing has been applied to the analysis of mammalian metallothionein (MT) extracts. In a rabbit-liver extract, four (MT-2C, MT-2A, MT-2D and MT-2E) out of six known MT sub-isoforms were unambiguously identif
