<921> WATER DETERMINATION 很多药典物品要么是水合物，要么含有处于吸附状态的水。因此，测定水分含量对于证实与药典标准的符合性是很重要的。通常，在各论中会根据该物品的性质，要求使用下面若干方法中的一个。偶尔，会允许在2个方法中任选一个。当该物品含有水合状态的水，按照具体各论中的规定，使用方法I（滴定...
In most cases, the minimum amount of specimen, in mg, can be estimated using the formula: FCV/KF in which F is the water equivalency factor of the Reagent, in mg per mL; C is the used volume, in percent, of the capacity of the buret; V is the buret volume, in mL; and KF is...
There are two different techniques for water determination by the Karl Fischer method, including volumetric KF titration and Coulometric KF titration. 3.1.1. Volumetric Karl Fischer Titration In the volumetric titration method, iodine is added using a burette to the solvent in the titration flask ...
based their approach on the XKF principle and constructed an observer for estimating position, velocity, attitude, underwater wave speed, rate sensor, and accelerometer biases, which demonstrated stability and achieved near-noise optimal performance [18]. Wang et al. integrated depth information into...
. Sodium tartrate may be used as a convenient water reference substance. Quickly add 75 to 125 mg of sodium tartrate (C4H4Na2O6·2H2O), accurately weighed by difference, and titrate to the endpoint. The water equivalence factorF,in mg of water per mL of reagent, is given by the formula...
