摘要: Abstract The dispersion of alumina particles on a glassy-carbon surface serving as modified electrode significantly enhances the amperometric detection cysteine and glutathione following liquid chromatography. With an applied potential 0.8 V vs. SCE, limits were 1.2 ng for 8 response was linear up to 600 1.8 μg glutathione. displayed high sensitivity stability easy inexpensive prepare.
