Question
what is the difference between M.C and LOD
 Question Submitted By :: Analytical-Chemistry
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
BY m.c WE CAN FINDOUT ONLY WATER CONTENT IN A DRUG
While trrough lod we can also know about non volatile
solvents present in a drug.

Answer
# 2
M.C. result gives only water content present in substance
while LOD result gives water content+solvent present in
substance. Thus, LOD content is always hIgher than M.C.

MC gives only % of water in a substance(Low melting range
substance).But LOD result is a combination of water
content and other volatile organic solvents.And more over
Melting range of a substance has to be considered in case
of LOD. Substances whichever is having high melting point
is required for LOD checking.

Answer
# 4
M.C =moisture content= the molecular water stored in the
molecule/it gives the exact water centent.(generally tested
by the KF titrator)

whereas

LOD=Loss on drying= unbound water + organic volatile
impurities.(in vacuum oven)

Answer
# 5
Moisture content gives value of bound and unbound water
content while LOD gives value of unbound water plus non
volatile solvent content
 
Is This Answer Correct ?    14 Yes 4 No

sample
LOD Means how much non voltail solvents and water present
in your sample

M.C BY K.F:GIVES THE INFORMATION ABOUT INTRAMOLECULAR AND
EXTRAMOLECULAR WATER CONTENT OF THE MOLECULE.


L.O.D: GIVE THE INFORMATION ABOUT ORGANIC SOLVENTS AND
EXTRAMOLECULAR WATER CONTENT IN THE MOLECULE

Answer
# 10
M/c (moisture content) - It determine that how many quantity of water present in supplied sample. It generally check by Karlfisher.
LOD ( lose on Drying)- determine both water and non-volatile substance in supplied sample. It done in oven at 110'C for 1hr.
