Testing limitations

Chromatographic purity is relative, not absolute

A purity figure is the relative peak area percent of the main peak within the reporting window of the method used. Species that do not elute in that window, do not respond to the detector, or co-elute with the main peak are not counted.

It is not a mass-balance purity figure and should not be read as one.

Identity support is not identity confirmation

Retention-time comparison against an appropriate reference standard and diode-array spectral comparison provide supporting evidence for identity. They do not confirm molecular identity. Confirmation requires mass spectrometry, which is a separate service.

Results apply to the sample as received

Findings apply to the specific material submitted, in the condition it arrived, at the time it was analysed. They say nothing about other units of a lot we did not test, nor about stability over time.

Method status is disclosed on every report

Each method is labelled as validated, in development, or development. A development method produces real data under defined conditions, but its performance characteristics have not been fully established. The label is always printed on the certificate.

No accreditation claim

Resolux Labs does not hold, and does not claim, ISO 17025 accreditation, GMP certification, regulatory approval or third-party certification. Any statement to the contrary is not ours.

Not a safety or fitness assessment

Nothing we issue evaluates sterility, endotoxin content, microbiological safety, biological potency, or suitability for any particular use, including human or veterinary use.
