Abstract
A method for the separation of hydrogen ion, characterized in that a substance having a conjugate base (A−) of an acid (HA) as a functional group is used as a stationary phase, and an electrolyte containing a cation having a larger ion exchanging force than that of hydrogen ion is used as an eluent. The method allows the selective separation of hydrogen ion and the quantitative analysis thereof with high precision.
Claims8
A method for separating hydrogen ion selectively by chromatography, which comprises
- using a substance with a functional group which is a conjugate base (A−) of an acid (HA) as a stationary phase, and
- using an electrolyte which contains a cation that exhibits higher ion exchanging force than hydrogen as an eluent.
An ion chromatography apparatus that separates hydrogen ion selectively, which comprises
- a separation column stationary phase that contains a substance having a conjugate base (A−) of an acid (HA) as a functional group, and
- an eluent that contains an electrolyte containing a cation that exhibits higher ion exchanging force than hydrogen.
