Extended Range of Pyridine-Free Reagents for Karl Fischer Titration
Oct 22 2012
The analysis of the water content of a sample by Karl Fisher titration can be carried out using a volumetric method or a coulometric one, depending on the amount of water present in the sample to be analysed.
Volumetric Karl Fischer titrations are suitable for determining the amount of water present in samples with a water content of 0.1% or higher. To analyse samples containing less than 0.1% water, coulometric Karl Fischer titration should be the method of choice, with detection limits down to 10ppm.
After years of experience in the manufacture of pyridine-free reagents for water analysis by volumetric Karl Fischer titration, Scharlab is introducing new Aquagent® reagents for coulometric Karl Fischer titration. So far, the range consists of 3 products: Aquagent® coulometric AG for instruments with a coulometric cell without a diaphragm, Aquagent® coulometric A, and Aquagent® coulometric GC, the latter two are suitable for use in coulometric cells with a diaphragm.
Scharlab also have 2 new water standards; Aquagent® Standard 1.0 and Aquagent® Standard 10.0 that, along with their Aquagent® Standard 5.0 and sodium tartrate dihydrate, complete the range of water standards available for Karl Fischer titration.
All Aquagent® products have stable end points that allow accurate and reliable results. They don't contain pyridine and are less toxic, resulting in increased laboratory safety and preventing unpleasant odours. Finally, they are suitable for analysing a wide variety of samples, permitting their use in many applications.
