In the pharmaceutical industry, Karl Fischer titration is used for the determination of water content in various drugs and excipients.The method is efficient, rapid, and accurate and provides reliable results. It allows the quantification of water content in samples ranging from ppm to 100%.
Karl Fischer titration is the most widely used technique to determine the water content in a sample. It is used in the analysiz of foods, pharmaceuticals and many chemicals, among others. 1. There are now three model levels; entry, mid-level, and flagship within each category (volumetric Karl Fischer, coulometric Karl Fischer, and automatic potentiometric titrator) My comment: I like the scale of the models as it can be helpful for those with varied budgets and needs.

There are now three model levels; entry, mid-level, and flagship within each category (volumetric Karl Fischer, coulometric Karl Fischer, and automatic potentiometric titrator) My comment: I like the scale of the models as it can be helpful for those with varied budgets and needs.In addition, coulometry is an absolute method and thus no titer determination is necessary. Recommended coulometry measuring range: 10 µg - 200 mg absolute water The 852 Titrando controls not only coulometric, but also volumetric Karl Fischer titration. For use with OMNIS Software, tiamo software, or Touch Control unit.Whatever your requirements – we have the right Karl Fischer titrator for you Our portfolio of Karl Fischer titrators includes compact all-in-one options for routine moisture determination as well as fully automated Karl Fischer systems for volumetric and coulometric Karl Fischer titration of water contents from 0.001 to 100%.Titration cell of a standard coulometric Karl Fischer (KF) automatic titrator. The oxidation of I − $$ {\mathrm{I}}^{-} $$ to I 2 $$ {\mathrm{I}}_2 $$ occurs at the anode in the anodic compartment containing the anolyte and the sample (in pale orange). A ceramic membrane (in orange) separates the anodic compartment from the cathodic .
A Karl Fischer titrator. In analytical chemistry, Karl Fischer titration is a classic titration method that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. [1] [2] Today, the titration is done with an automated Karl Fischer titrator. Karl Fischer (KF) coulometric titration . I.

Whatever your requirements – we have the right Karl Fischer titrator for you Our portfolio of Karl Fischer titrators includes compact all-in-one options for routine moisture determination as well as fully automated Karl Fischer systems for volumetric and coulometric Karl Fischer titration of water contents from 0.001 to 100%.Compact all-in-one solution for Karl Fischer titration Convenient touch screen display: start your favourite methods at the click of one button and check your system status at a glance No contact with the KF reagents using Dosino . I recommend carrying out a volumetric or coulometric Karl Fischer titration using a certified water standard as sample. In volumetry, you can carry out a threefold titer determination followed by a determination of a different standard. Then, you can calculate the recovery of the water content determination of the standard. Coulometric KFT In coulometric Karl Fischer, iodine is generated electrochemically in situ during the titration. Water is quantified on the basis of the total charge passed (Q), as measured by current (amperes) and time (seconds), according to the following relationship: Q = 1C (coulomb) = 1A x 1S Where 1mg H2O= 10.72 C Dr. Sajjad Ullah, ICS UoP
