  • The high-performance liquid chromatography method was performed for test method development of related compounds in pharmaceuticals. Using reverse-phase column and gradient elution of 1 % acetonitrile-acetonitrile: H20:triethylamine (70:30:0.5), lansoprazole, 2-hydroxybenzimidazole, 2-mercaptobenzimidazole, lansoprazole sulfone, lansoprazole sulfide could be individually identified and quantitated.
