| Research Abstract |
A microbiological assay which is cumbersome and less precise was used widely for quantitation of vitamin B_<12>, but we examined a new method using the high performance liquid chromatograph (HPLC) as a simple, easy and quick analysis method. It was suggested that condensation of analyte and removal of impurities by using solid phase extraction cartridge was allowed the quantitation of ultralow concentration of vitamin B_<12> in HPLC
