I-1. Questions & Answers about Karl Fischer Reagents
Characteristics of the Aquamicron Series
When using the Aquamicron Series of electrolytes it is important to
understand the following characteristics of the products.
a) Very small quantities of water (about 10ug) can be measured
accurately.
b) Titration procedures are very simple.
c) Measurements can be carried out quickly (1-10 minutes).
d) It is not necessary to assess the titer of the reagent.
e) The reagent can be used repeatedly.
f) The composition of the solvents has been enhanced to make them
suitable for immediate use with various samples. This eliminates the
troublesome task of adding other solvents.
1. General-Purpose Electrolytes
The general-purpose Aquamicron Series of products are ideally constituted
to facilitate Karl Fischer reactions with solvents, including methanol and
propylene carbonate. Sample solubility is excellent, and even trace amounts
of moisture can be extracted and titrated coulometrically with ease. These
products also offer superior reagent stability, which is the most important
requirement when measuring minute amounts of water. This means that
measurements can be taken with good reproducibility.
The Aquamicron Series is suitable for a wide range of products including
aromatics and other organic solvents, petroleum products, inorganic
products and gas products.
They are also the ideal reagents for the water vaporization method. A
particularly convenient feature is the fact that they can be used immediately
without the need to add other solvents. Aquamicron products have an
excellent reputation for use in day-to-day moisture measurement for plastics
and other solid samples.
