1. <strong>Karl</strong> <strong>Fischer</strong> Reagent SS-Z, SS<br />
Chapter I: Basic Knowledge<br />
Initially the titer <strong>of</strong> <strong>Karl</strong> <strong>Fischer</strong> reagents was unstable, and it was necessary<br />
to use them in the extremely inconvenient form <strong>of</strong> binary solutions.<br />
Mitsubishi Chemical was the first manufacturer in the world to perfect a<br />
single solution version, which it called "<strong>Karl</strong> <strong>Fischer</strong> Reagent SS". In the 50<br />
years since that time, Mitsubishi Chemical has continued to enhance and<br />
expand its technology, and today enjoys an excellent reputation for its<br />
superior products.<br />
Mitsubishi Chemical has also developed <strong>Karl</strong> <strong>Fischer</strong> Reagent SS-Z, which<br />
is pyridine-free and does not contain chlor<strong>of</strong>orm or methyl cellosolve. Users<br />
can choose from an extensive product range, as listed below.<br />

<strong>Karl</strong> <strong>Fischer</strong> Reagent SS-Z:<br />
Pyridine-Free and Methyl Cellosolve-Free Types<br />
Instead <strong>of</strong> pyridine, <strong>Karl</strong> <strong>Fischer</strong> SS-Z contains a solid amine. As a result,<br />
the product is free <strong>of</strong> the pyridine odor. All the ingredients required to<br />
implement <strong>Karl</strong> <strong>Fischer</strong> reactions stoichiometrically are included in a single<br />
solution. The product is available in either 5mg/ml, 3mg/ml or 1mg/ml titer.<br />
