摘要：
A reagent for measuring a specific type of ions comprising a maltose derivative having a chromogenic group introduced into the reducing end, such as 2-chloro-4-nitrophenyl maltose or paranitrophenyl maltose, is provided. By using the present measurement reagent, a specific type of ions can be exactly measured with no influence of amylase from samples, and accordingly, the ions can be conveniently and exactly measured in biological samples such as serum or urine.
