Sample requirements
- Clearly identified, representative sample
- Expected water range, when known
- Matrix and storage information
- Tightly sealed packaging that limits atmospheric moisture
- Sufficient sample quantity
- Applicable SDS and safety information
Important limitations
- Poor solubility, viscosity, oils, reactive matrices, or specialized introduction may require extra preparation.
- Substances that react with iodine, generate or consume water, release water slowly, or interfere with the endpoint may require method modification.
- Results may be affected by atmospheric moisture, handling, homogeneity, and stability.
- Compendial, GLP, GMP, regulatory, or validated requirements must be identified before submission.
