TAN (Total Acid Number)

The titration curves for every concentration of the CONOSTAN family of TAN standards have more prominent inflection points and a wider difference between the starting pH and final pH during titration, in comparison with other suppliers.  At minimum concentration for TAN standards, the pH change in the titration curve is now greater than even the highest concentrations of competitive standards.  Because the inflection point is more prominent, CONOSTAN TAN standards offer uncertainties less than 1% of stated concentration providing customers the opportunity for better calibration of their titrator and TAN titration method.
