The analysis of stock in trade and raw material contains an important method called Non-Volatile Matter Analysis which represents the mass percentage of solid material in a specimen after the elimination of other elements by heating or evaporization. It has a vital role in armada-like areas of pharmaceuticals, chemicals, and coatings since it helps in the determination of purity, stability, and quality of the specific product. Through determination and calculation of the quantity of material that does not vaporize, NVM analysis leads to product quality and consistency compliance with the standards of production.
Non-Volatile Matter (NVM) Analysis
Introduction to NVM Analysis
Instrumentation of NVM Analysis
The most common instrument used in non-volatile matter (NVM) analysis includes a balance to weigh the sample before and after digestion, and an oven or heat lamp to heat the sample at a specific temperature leading to evaporation of the volatile components. It may also include a desiccator for containing moisture during cooling of the sample, or glassware or metal containers for the same sample.
Strengths and Limitations of NVM Analysis
Strengths
- Used to get an accurate determination of the residue that is left after the volatilization process to determine the makeup of the materials.
- Crucially relevant in industries like the manufacture of drugs and medicine, chemicals, and food processing industries.
- Can be fully automated which means that you will not have manual interferences reducing the rate of errors.
Limitations
- May not give other attributes of the identity of the compound if the test only provides a rudimentary characterization of the non-volatile residue.
- A measure of the environment with higher order in order not to go wrong.
- Since only gas chromatography was used method only nonvolatile species could be separated and quantified while volatile species were undetermined.
NVM Analysis Related Techniques
NVM Analysis is related to techniques including Thermogravimetric Analysis (TGA), High-Performance Liquid Chromatography (HPLC), and Gas Chromatography (GC).
