Analysis Note

The concentration (efficiency) of Karl Fischer titrants decreases over time. Therefore the titer, being a corrective factor that compensates for this effect as well as variations of equipment, personal handling and laboratory conditions, must be determined directly after opening a new bottle and should be verified at regular intervals.
