ReAquant Reagent System The ReAquant Reagent System rep- resents a breakthrough in the titri- metric end-point determination of water (moisture) content. It consists of ReAquant Titrant and ReAquant Solvent. Used together, they offer distinct advantages over convention- al Karl Fischer methods to analysts involved in the determination of "free" water for pharmaceutical, petro-chemical and industrial chem- ical quality control. ReAquant Solvent Is a methanolic solution containing some components of the titration system, and is used for the dissolu- tion and dilution of samples. ReAquant Titrant Contains methanol and iodine. The approximate titer, as stated on the label, is 3.5 mg of water per milliliter. Π No Odor Problem J. T. Baker ReAquant reagents are completely free of both pyridine and sulfur dioxide.
