Inorganic Residue Profiling by Gravimetric Testing
In the pharmaceutical sector, ensuring product purity is paramount. Inorganic residues in drug substances and excipients can have a significant impact on formulation stability, efficacy, and safety. Gravimetric testing provides an accurate means to quantify these residues, offering reliable data for compliance with regulatory standards.
The process involves heating the sample under controlled conditions to volatilize organic components while leaving inorganic constituents behind. The weight difference before and after this procedure measures the amount of inorganic residue present. This method is particularly useful in characterizing materials that contain both organic and inorganic compounds, ensuring accurate chemical characterization.
The gravimetric approach adheres to stringent quality control protocols as outlined in international standards such as ISO 14635:2007 for sample preparation and ASTM E192-18 for drying procedures. The precision of this technique ensures that even trace amounts of impurities are detected, contributing significantly to the overall quality assurance process.
