High-performance liquid chromatography (HPLC) is an analytical technique used to separate components of a sample and evaluate the resulting chromatographic profile.
What HPLC can support
Under a defined method, HPLC can support statements about relative purity and the presence of chromatographic components. It is a useful part of product verification when paired with correct sample identity and documentation.
What HPLC does not prove by itself
An HPLC result alone does not establish sterility, human safety, therapeutic efficacy, or suitability for ingestion, injection, or another unapproved use.
Why documentation matters
The most useful result is connected to a product, batch, method, date, and report reference. Analytical results should always be reviewed alongside the product identity, method, batch reference, and supporting documentation.
Freedom quality resources
Use the quality standard and Lab Reports & COAs for product-documentation context.
