| 摘要 |
The invention relates to a method for measuring anions by suppressor-system or non-suppressor-system ion chromatography, comprising using a column for ion chromatography, which is packed with an alkali-resistant anion exchanger comprising porous polymer particles, in combination with an alkaline eluent, said porous polymer particles comprising an alkali-resistant polymer substrate having bonded thereto through a spacer a nitrogen-containing heterocyclic group having a quaternary ammonium structure which measurement is used for the measurement of halogen oxide ions. |
