What Is Residue & Impurity Quantification?
Residue & Impurity Quantification analyses are critical physicochemical tests conducted to detect and quantify residues, impurities, and undesirable components that may be present in products. These studies play a significant role in the quality and safety assessments of pharmaceuticals, medical devices, biocidal products, cosmetic products, raw materials, and various chemical formulations.
Low levels of impurities or residues may form in products due to production processes, raw materials, packaging materials, or storage conditions. Ensuring that these components remain within internationally accepted limits is of critical importance for product safety and regulatory compliance.
At NanoTox, within our Physico-Chemical Test Unit, we offer reliable residue and impurity analysis services using advanced analytical technologies and an infrastructure that adheres to GLP principles.
Purpose of Residue & Impurity Quantification Tests
These analyses aim to identify unwanted components in products and determine their quantities.
Bu çalışmalar sayesinde:
- Product purity is assessed,
- Residue levels are determined,
- Ürün güvenliği desteklenmektedir,
- Production processes are validated,
- Düzenleme gereksinimleri karşılanır.
The data obtained helps demonstrate that products comply with quality standards.
Why Are Residue and Impurity Analyses Important?
In addition to active ingredients, impurities or residues present at low levels can also have significant effects on product safety. While some impurities may reduce product efficacy, others may pose toxicological risks.
For this reason, residue and impurity analyses are widely applied, particularly in:
- Identifying degradation products in pharmaceutical products,
- Evaluating process residues in medical devices,
- Controlling production-related impurities in biocidal products,
- Identifying undesirable components in cosmetic products,
- And in raw material quality control studies.
