In one-component systems, all reagents participating in the Karl Fischer reaction are supplied in one product. Our Aquagent^® Composite.

Aquagent^® Composite 5 is for general purposes while Aquagent® Composite 5K is specific for the analysis of ketones and aldehydes.

The sample must be dissolved in an anhydrous liquid to be titrated. Dry methanol is used in conjunction with Aquagent^® Composite 5 or Aquagent^® Composite 2

Methanol cannot be used as solvent for the analysis of ketones and aldehydes. It must be substituted by Aquagent^® Medium K.

One-component reagents are very simple to use. On the other hand, they must be titrated frequently due to the reactivity of their components.

Expiry date for these reagents is typically two years.

We add a label on each bottle of Aquagent^® Composite, where the user can write down reagent titration dates and obtained titre. Thus, he has the whole titration history of each bottle at a glance.

In the two-component system, the solvent doesn’t act only as a solvent medium, but also contains part of the reagents. This allows longer shelf-life and avoids the need for frequent titration.

The use of two component reagents is more expensive but it presents several advantages:

• Faster reaction
• Less consumption of titration reagents
• Better stability of the reagents
