Las Vegas, Nevada · Independent laboratory
Independent analytical testing for peptides and research compounds.
HDChroma characterises what is actually in a vial: identity, chromatographic purity, content, residues and microbial attributes — reported against the method used and released only after independent quality review.
Results apply to the sample as received and to the determinations listed on the certificate. Scope, turnaround and any registration or accreditation status are confirmed per engagement and available upon request.
Certificate integrity model
- 01DraftData entered by authorised staff. Watermarked, never public.
- 02Analyst reviewTechnical check against raw data and method.
- 03QA reviewIndependent release decision by a second person.
- 04PublishedLocked snapshot, SHA-256 fingerprint, public lookup.
Amendments create a new version; the superseded version stays in the audit trail.
Why the report can be trusted
Controls that sit between an instrument reading and a signed certificate.
Analytical value comes from the discipline around the measurement, not the measurement alone.
Transparent scope
Every certificate states exactly which determinations were performed. Anything outside that list is reported as not tested rather than implied.
Method-linked reporting
Each result carries the internal method code and version used to generate it, so a number can always be traced back to a procedure.
Controlled chain of custody
Receipt condition, storage, handling and analyst assignment are recorded as timestamped events against the sample record.
Independent QA release
The analyst who generates data cannot release it. A separate quality reviewer approves, locks and issues the certificate.
Secure records
Raw data references and client information stay private by default. Public lookup exposes only the issued certificate content.
Versioned amendments
An issued certificate is immutable. Corrections create a new version and the superseded record remains in the audit trail.
Service overview
Five areas of determination.
Identity & composition
Accurate-mass confirmation, structural corroboration and sequence-level work for peptides and small molecules.
Purity & content
Chromatographic purity profiling, quantitative assay against reference material, water content and counter-ion determination.
Residues & elemental impurities
Headspace determination of process solvents and elemental screening of catalyst and container-derived metals.
Microbiology
Bacterial endotoxin, bioburden and sterility determinations performed on request within defined scope.
Stability & method work
Time-point programmes, forced-degradation studies and method development or transfer support.

Process
From request to verifiable certificate.
- 01
Request
You describe the material and the questions you need answered.
- 02
Scope & quote
We confirm determinations, turnaround and any limits before work begins.
- 03
Intake
Sample receipt, condition check and custody record are created on arrival.
- 04
Analysis
Determinations are executed under referenced internal methods.
- 05
Review
Analyst review, then independent quality review of data and certificate.
- 06
Release
The certificate is locked, fingerprinted and made verifiable.
Quality system
ALCOA+ data practice, versioned methods, independent release.
Records are attributable, legible, contemporaneous, original and accurate — plus complete, consistent, enduring and available. Retention periods and record scope are configured by laboratory management and stated per engagement.
