Volumetric Karl Fischer Titrator
The volumetric karl fischer titrator adopts the newest mechanical-electronic technology with humanistic interface. It is reliable with wide measuring range (0.001%-100%), high precision and affordable for users. It can determine crystal water, adsorbent water in gas, liquid, solid samples.
It can automatically analyze, absorb and discharge liquid, adjust instrument failure, protect important parts, calibrate electrode parameters, etc.
There are two different techniques for water determination by Karl Fischer Titration: Volumetric KF titration and Coulometric KF titration.
1. The Volumetric Karl Fischer Titration is suitable for determination of water content down to 1% of water. The sample is dissolved in Karl Fischer Solvent (usually methanol based) and the iodine is added as a part of a KF Reagent containing sulfur dioxide and iodine dissolved in pyridine and methanol. The endpoint is determined potentiometrically.
2. The Coulometric Karl Fischer analysis requires only one, iodide-containing, solution. Iodine needed for KF reaction is produced by anodic oxidation of iodide from solution and the endpoint is detected electrochemically. Coulometric determination is best suited for samples with less than 1% of water.
The GDD-1A Volumetric Karl Fisher Titrator adopts the newest mechanical-electronic technology with humanistic interface. It is reliable with wide measuring range (0.001%-100%), high precision and affordable for users. It can determine crystal water, adsorbent water in gas, liquid, solid samples.
Volumetric karl fischer titrator can automatically analyze, absorb and discharge liquid, adjust instrument failure, protect important parts, calibrate electrode parameters, etc.
1. Volumetric karl fischer titrator has dual platinum electrode polarization voltage to judge and show the reaction endpoint,then stop titration.
2. Fully sealed system, in order to avoid ambient moisture's penetration.
3. By the function keys,the instrument can absorb reagent, measure, show end point, absorb solvent, discharge waste fluid, stir and adjust speed.
4. Displaying the mixed results simultaneously, titration dynamically display and automatic memory of test data.
5. Automatically deduct drifting value,automatically track the ambient moisture drifting and make sure the test data is precise.
6. The system is fully sealed,it can renew the solvent and discharge waste fluid automatically, to avoid leak out toxic solvent.
7. Instrument status, dip stool sample volume, present time and drifting value,etc could be displayed instantly
8. The Karl Fisher Titrator runs smoothly, low noise.
