Determination of Response Factors for Analytes Detected during Migration Studies, Strategy and Internal Standard...

Area of Science:

• Pharmaceutical analysis
• Analytical chemistry
• Mass spectrometry

Background:

• Migration studies detect contaminants in pharmaceuticals from formulation-material interactions.
• Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) are used for wide-scope screening.
• Mass spectrometry detectors lack universal response, necessitating uncertainty factors in regulatory evaluations.

Purpose of the Study:

• To evaluate the response of common species in migration studies.
• To develop a strategy and mechanism for classifying detected contaminants.
• To assess the robustness of an LC-MS methodology using Design of Experiments (DoE).

Main Methods:

• Analysis of a representative sample of species typically found in migration studies.
• Implementation of Design of Experiments (DoE) for Design Space generation.
• Evaluation of an LC-MS based methodology for robustness.

Main Results:

• A strategy and evaluation mechanism for classifying detected species was created.
• The robustness of the LC-MS methodology was assessed under varying conditions.
• The study provides insights into the response variability of analytes in migration studies.

Conclusions:

• The developed strategy aids in the acceptable classification of detected species in pharmaceutical migration studies.
• The evaluation of the LC-MS methodology confirms its robustness and suitability for migration analysis.
• This research contributes to improving the reliability and safety assessment of pharmaceutical products.
