Alfa Chemistry | Professional Mass Spectrometry (MS) Platform for Drug Analysis
Pharmaceutical analysis is critical for ensuring the quality, safety, and efficacy of drugs. Accurate measurement of active pharmaceutical ingredients (APIs), drug formulations, and degradation products is a core component of research and development, regulatory compliance, and quality control.
At Alfa Chemistry, we specialize in mass spectrometry (MS)-based pharmaceutical and drug analysis, providing high-resolution, high-sensitivity, and high-throughput solutions suitable for a wide range of pharmaceutical compounds. Our services strictly adhere to pharmacopeia standards and regulatory requirements, helping clients obtain reliable data for both research and industrial applications.
Why Use MS for Pharmaceutical Analysis?
Mass spectrometry (MS) has become a core technology in drug development and quality control, offering the following advantages:
- High Sensitivity: Capable of detecting trace levels of active pharmaceutical ingredients (APIs) and impurities (ng/mL – μg/mL).
- High Selectivity: Accurately differentiates drug molecules, metabolites, and degradation products.
- Structural Elucidation: Identifies unknown impurities and degradation pathways.
- Wide Applicability: Suitable for complex formulations and biological samples (plasma, serum, tissue).
Alfa Chemistry's MS platform enables precise quantitative and structural analysis of raw materials, drug formulations, and degradation products, ensuring compliance with pharmacopeia standards and regulatory requirements.
