Extractables & Leachables from Container and Closure Systems
ICH Topic Q6A requires the determination of the level of extractables and leachables from containers and closure systems. Development and stability data should demonstrate that extractables from container/closure systems are consistently below levels that are acceptable and safe. M-Scan has developed in-house validated methods for the analysis of plasticizers and leachables from rubber seals, tubing and containers as well as analysis methods for other extractables below.
-
Plasticizers are analyzed by freeze drying and solvent extraction Gas Chromatography-Mass Spectrometry (GC-MS).
-
Semi-Volatile Organic Compounds are analyzed by solvent extraction GC-MS.
-
Detergents. Non ionic and cationic detergents are analyzed by positive ion matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF) or positive ion fast atom bombardment mass spectrometry (FAB-MS).
-
Anionic detergents are analysed by freeze drying followed by negative ion FAB-MS.
-
Oligomeric and Polymeric Species are analyzed by freeze drying followed by direct Evolved Gas Analysis-Mass Spectrometry (EGA-MS).
-
Residual Solvents are covered by the guideline in ICH Topic Q3C. Buffer salts or other solid material added during manufacture can be analyzed for residual solvents by Thermal Desorption GC-MS. (see M-Scan publication ‘Determination of Solvent Residues in Medicinal Products).
-
Adsorbed Products adhering to the surface of the container are analyzed by a determination of the amino acid concentration on a known area of the empty container.
-
TOC is a quick, accurate and inexpensive screening protocol for hydrocarbon contamination and can be used for determining the efficiency of cleaning protocols as required by The Code of Federal Regulations Title 21 CFR 211.6
