HANNA款微電腦卡爾費(fèi)休庫侖法水分測(cè)定儀

HI904微電腦卡爾?費(fèi)休庫侖法水分測(cè)定儀

微量5%或1ppm含水量的測(cè)定: 含水量很低的樣品（1ppm to 5%），由于含水量很少，常規(guī)采用卡爾費(fèi)休庫侖法水分測(cè)定，加入庫侖法卡爾費(fèi)休試劑，通過智能反應(yīng)池，在幾分鐘內(nèi)就能獲取的水分測(cè)定數(shù)據(jù)，適用于固體、液體微量水分快速測(cè)定。

HI904 HANNA款微電腦卡爾費(fèi)休庫侖法水分測(cè)定儀-產(chǎn)品介紹

Features

? More precise, better accuracy than other water content analysis methods
? Measures 1ppm to 5%
? Low sample volume and preparation is easy
? Can be used for liquids or solids*
? Specific to water – independent of presence of volatile substances
? Closed reagent handling system with integrated diaphragm air pump maintains a dry environment
? Easily transfer methods and results (of drift analysis or titrations) to PC via the USB port
? Choose from diaphragm or diaphragm-less generator cells, depending on the specific application
? Compact shape will fit on any laboratory bench (not composed of many modules that can take up space)

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).
