Compact Salt Analyzer

April 19, 2010
The salt analyzer achieves determination of chloride ions by coulometric titration method. Measurement occurs when silver ions produced from the silver wire by electrical oxidization in a special electrolyte react with chloride ions in the samples. The concentration of Cl or NaCl is calculated from the quantity of electricity required to produce silver ions. Easy maintenance means no standardization of reagent is required in coulometry. Operation is simple with an injection of the sample solution into the electrolyte-filled measuring vessel to obtain rapid and accurate results. Small footprint design (310mm W x 270mm D) saves bench space. Rapid measurement is achievable within 20 seconds to measure 20µL or 1-percent NaCl standard. Colored samples are also accurately measurable with no problem in potentiometric end-point detection method. Reusable electrolyte for several measurements achieves cost savings. The Mercury-free and trouble-free sleeve-type reference electrode is adopted for safety.
