Analytical system

The analytical engine.

Every result begins with controlled separation, detection, quantitation, review and traceable reporting — executed against an approved method version, not an ad-hoc run.

Chain of custody

One sample.
One ID.
One traceable history.

A Resolux Sample ID is issued when the order is created and never changes. Accessioning, preparation, autosampler position, analysis, review and certificate release are all recorded against that single identifier.

Reporting

A certificate
that can be checked.

Every released certificate carries the sample identifier, the method and version used, the analyst and reviewer, the release status and a verification reference. Corrections are issued as a new version — nothing is silently edited.

What we report

  • Chromatographic purity
  • Quantitative amount
  • Amount per vial
  • Chromatographic data, including retention behaviour
  • DAD spectral information where supported
  • Method, version and report information

What we don't overstate

  • HPLC-DAD alone does not conclusively establish molecular identity.
  • Endotoxin testing does not establish sterility.
  • Results apply to the submitted sample.
  • Analytical conclusions are limited to the scope of the performed method.

Additional capability

Bacterial
endotoxin testing

Bacterial endotoxin testing measures endotoxin content — a lipopolysaccharide pyrogen associated with Gram-negative bacteria — under the laboratory's configured method. It is available as a standalone test or added to Complete Peptide Analysis on the same submitted sample.

Standalone test
$189
Added to Complete Peptide Analysis
In the order builder

An endotoxin result does not establish sterility, absence of all microorganisms, biological potency or suitability for human use.
