Instrumentation and Practice

Evidence begins with the measurement.

ZAVCO combines chromatographic separation, UV detection and mass-spectral evidence to report what the submitted sample supports—and the limits of what it does not.

Chromatography

Agilent 1100 HPLC-DAD

Reversed-phase separation with diode-array detection supports purity assessment, retention-time evaluation and quantitative analysis when an appropriate calibration is applied.

Mass Spectrometry

Agilent 6130 LC/MSD

Electrospray ionization mass spectrometry provides molecular-mass evidence from observed peptide charge states at the chromatographic retention window.

Reporting discipline

Practices are modeled around traceability, controlled methods and review without claiming accreditation ZAVCO does not hold.

Traceable samples

Orders, submitted vials, preparation records, analytical runs and reports remain linked by assigned identifiers.

Controlled revisions

Issued PDFs remain fixed. Corrections create a new revision while the earlier report is retained as superseded.

Clear limitations

Each report distinguishes analytical evidence from sterility, biological activity, safety and suitability claims.
