Thermo Scientific™ OQ/PQ Substance (Caffeine) is a certified, ready-to-use reference solution specifically designed for Operational Qualification (OQ) and Performance Qualification (PQ) of UHPLC (Ultra-High Performance Liquid Chromatography) systems. Supplied at a concentration of 10 mg/mL caffeine in water, this solution is ideal for validating system suitability, wavelength accuracy, retention time reproducibility, linearity, and UV detector performance in compliance with regulatory guidelines.
Caffeine, a well-characterized and stable compound, is widely used as a system suitability standard due to its sharp UV absorbance at 273 nm, good solubility, and consistent retention characteristics under reversed-phase chromatographic conditions.
Key Features and Benefits
- Pre-formulated Standard: 10 mg/mL caffeine in water; no dilution or preparation required
- Designed for UHPLC Validation: Ideal for routine OQ/PQ protocols and system suitability testing
- High Purity & Stability: Formulated for reproducibility, accuracy, and shelf-life consistency
- UV Detection Compatibility: Strong absorbance at 273 nm; suitable for DAD and UV detectors
- Regulatory Support: Supports qualification under GMP/GLP-compliant workflows
