Water content that contains N-methylpyrrolidone as main ingredient can be determined by using the combination of the AQ-2200 or AQ-300 Coulometric Karl Fischer Titrator and the EV-2000L Oil/grease evaporator. Since the sample is highly viscose and not soluble in toluene,reducing the sample size to about 0.2g per measurement is a point to perform a successful measurement.
