The Aquamax KF Online is based on the Karl Fischer titration according to ASTM D 6304, procedure C (oven method). The sample is taken regularly from the running process and dosed contamination-free into the extraction chamber. Only the water content is transported into the titration cell, so that reagent lifetimes of more than 2000 measurements can be achieved. The measuring principle allows precise determinations in the trace range with high detection sensitivity.
