Answer / vaishali
In LOD test both organic solvents and water content are
determined.
& in karl fisher titration only water content is determined.

Answer / vikky
In water by KF test we can determine water content only
whera as in LOD test we can determine % of volatile
Solvents and water in drug substance.

Water By KF is to determine Bound or in bound water which
is present in Drug molecule But in LOD determine organic
volatile impurities evapoated on drying the sample at
specified condition

Answer / sudha
In water by KF test we can determine only water content
wher as in LOD test we can determine % of volatile
Solvents and water in drug substance based on nature of
melting range. If melting range is LESS than 105°c then
LOD COUNTS AS % of volatile Solvents only.

Answer / falguni
In LOD We can measure loss of Volatile solvent (depend on
their boiling point)and also loss of adsorbed water (upto
some extent). In karl fischer we can find total content of
water, whether it is adsorbed or absorbed.
