Actually Karl Fischer titration and loss on drying (LOD) are the methods, which is used for
determining moisture content in a product. We detect LOD by moisture analyzer machine.
Karl Fischer Titrator: KF is a
method, which measures only the water content (i.e. it's water-specific)
in a product sample. Karl Fischer titration is a
chemical method. It involves adding a reagent to the sample to cause a reaction
that converts the water in a product to a non-conductive chemical.

LOD-Loss On Drying: LOD that means loss on drying we determine lod by the moisture analyzer machine, lod measures the total change in weight of a material as a
result of drying. For some products,
components such as alcohol or fat evaporate with the water. Therefore, the LOD
method measures both the water and volatile impurities such as those mentioned
previously Loss on Drying compares the
weight of a product before and after it is dried. This difference in weight is
taken as the percentage of moisture in the product.

Finally, we can say by the Karl Fischer Titrator we only detect what amount of water into the substance, but by the moisture analyzer we can not detect what amount of water like any other liquid substance into the materials. So here we detect what percentage of any kind liquid present into the materials.
For Example: (LOD-Loss On Drying) Suppose 50 gm materials used in moisture analyzer machine after drying determine how percentage weight loss of this 50 gm materials, so we say loss on drying.
sir in kf titration we are using dried methnol rather than normal methnol?????what is the difference between dried methnol and methnol???

ReplyDeletecan you tell me plz another difference?
