Vitamins
- Vitamins, especially for pharmaceutical and food applications, require very high
purity.
- Impurities can affect potency, stability, and safety.
- The assay measures the actual amount of the vitamin present in a sample.
- This is crucial for ensuring accurate dosing and labeling.
- Vitamins can be sensitive to heat, light, moisture, and pH.
- Specifications often include requirements for stability under various storage
conditions.
- Limits on heavy metals (e.g., lead, arsenic, cadmium) are essential for safety.
- For vitamins used in food and pharmaceuticals, microbiological limits are crucial.
- Particle size can affect solubility, bioavailability, and handling.
