HANNA款微电脑卡尔费休库仑法水分测定仪

HI904微电脑卡尔?费休库仑法水分测定仪

微量5%或1ppm含水量的测定: 含水量很低的样品（1ppm to 5%），由于含水量很少，常规采用卡尔费休库仑法水分测定，加入库仑法卡尔费休试剂，通过智能反应池，在几分钟内就能获取的水分测定数据，适用于固体、液体微量水分快速测定。

Introducing the newest addition to Hanna’s family of Titration Systems: the HI 904 Coulometric Karl Fischer Titrator. The HI 904 excels at determining water content in
extremely small concentrations (1 ppm to 5%) and requires no titrant, instead using a generator electrode.
A pulsed DC current is applied to the generator electrode and results in oxidation of free iodide to iodine (the titrant) at the platinum anode. Alcohol, sulfur dioxide and base
(pyridine or imidaole) present in the reagents react to form a salt that is oxidied by the generated iodine. This reaction consumes water present in the cell in a 1:1 ratio
(iodine:water). Once all of the water is consumed, the excess iodine is detected using a bilvoltammetric detector electrode and signals the end of the titration. The result is
calculated from the amount of current applied to complete the reaction and the length of time that the generator electrode is active (A?s, or Coulombs).
