Karl Fischer Reagents for Moisture Analysis in laboratories
In chemical analysis and laboratory analysis, precise measurement of moisture is essential. Karl Fischer Reagents are the world standard in the industry for accurate water content measurement of gas samples, liquid samples, and solid samples. No matter you’re analyzing food products, petrochemicals, cosmetics, or pharmaceutical products, Karl Fischer titration ensures your results to be consistent, accurate, and as per industry standards. At Dawn Scientific, we provide with pride Karl Fischer Reagents of high purity, delivering superior performance in coulometric and volumetric moisture analysis.
In this blogpost, we are going to learn about what are Karl Fischer reagents, why use karl Fischer Titration for Moisture Analysis, how Karl Fischer Titration works, applications and advantages of KF reagents.
What Are Karl Fischer Reagents?
Karl Fischer Reagents are specialized blends of chemicals used in Karl Fischer titration, a method expressly developed to measure trace and total water content in a variety of substances. The reagent typically contains iodine, sulfur dioxide, a base (typically imidazole), and a solvent compatible with it (for example, methanol). When contacted with a sample, these reagents react selectively with water molecules, so it is feasible to obtain highly accurate measurements.
In volumetric (best suited for high moisture content) and coulometric (best suited for low moisture sample) designs, our Karl Fischer Reagents are engineered to offer maximum operator safety, shelf life, and stability.
Why use Karl Fischer Titration for Moisture Analysis?
Compared with other methods of moisture determination such as loss on drying or infrared analysis, Karl Fischer Titration offers:
High accuracy and reproducibility
Rapid analysis times
Discriminating measurement of water content
Universality of use across many different materials and industries
Karl Fischer Titration is a vital tool for any lab that must conduct moisture analysis to parts-per-million (ppm) levels.
How Karl Fischer Titration Works
Karl Fischer Titration is a chemical method of measuring the amount of water in a sample very precisely. It is founded on a reaction between iodine and water, but under the influence of sulfur dioxide and a base, and typically in an alcoholic solvent.
Two major types of Karl Fischer titration exist:

Frequently Asked Questions (FAQs)
What is the difference between volumetric and coulometric Karl Fischer titration?
Volumetric KF titration is applied in high water content samples, whereas coulometric is best suited for trace moisture (below 1%). The principal difference is in the addition of iodine—produced volumetrically or electrochemically.
Are Karl Fischer Reagents dangerous?
While newer preparations are less dangerous, KF reagents do expose one to chemicals like iodine and sulfur dioxide. One does require proper PPE, ventilation, and storage.
How long do Karl Fischer Reagents last?
Reagents will typically last 12–24 months if properly stored in tightly sealed containers in the dark and away from moisture. Always refer to the manufacturer’s recommendations.
Is Karl Fischer Reagent compatible with any titrator?
Our reagents are generally compatible with any of the major KF titrators. Consult compatibility with your instrument or phone our staff.
