| 摘要 |
<p>This invention provides a washing storage solution (22), which can substantially completely remove contaminants such as transition metals and alkali metals deposited on the surface of a glass electrode that comprises a glass comprising lithium and can restore performances as an electrode such as responsiveness and reproducibility in the measurement to an initial state or a state better than the initial state. The washing storage solution (22) is characterized by comprising at least one reducing reagent having a reduction behavior. Examples of reducing reagents include hydroxylammonium chloride, sodium hyposulfite, sodium hydrogen sulfite, sodium thiosulfate, sodium hypophosphite, ascorbic acid, and titanium oxide.</p> |
