HPLC
High-performance liquid chromatography. Separates the sample into its components and reports the share attributable to the target compound — the purity figure on the certificate.
TESTING & QUALITY
Every lot, one workflow.
How every lot is documented.
A sample from every lot is analyzed by Freedom Diagnostics, an independent third-party laboratory, using HPLC and LC-MS. The report becomes the lot's Certificate of Analysis.
A sample from every lot is analyzed by Freedom Diagnostics, an independent third-party laboratory, using HPLC and LC-MS. The resulting Certificate of Analysis is published to the library and linked to the lot number on the vial label. Documentation describes the material; it says nothing about use.
Seven steps, one record.
Material intake
Incoming material is logged with source, receipt date, nominal quantity and SKU. Nothing enters the catalog without a record.
Lot assignment
A lot number in the format SC-YYMM-NNN is assigned and printed on every vial label of that lot.
Sampling
A sample is drawn from the lot and dispatched to the independent laboratory with the lot number and nothing else.
Independent laboratory analysis
Freedom Diagnostics analyzes the sample by HPLC and LC-MS and issues its report.
COA review
The report is checked against the lot record — compound, quantity, lot number, date.
Publication
The certificate is published to the COA library and the lot record at sc-peptides.com/coa/[LOT] goes live.
Traceability
Retired lots move to the archive; their documents remain available so any vial can be traced for as long as it exists.
Methods reported on the certificate.
METHODS IN USE
LC-MS
Liquid chromatography with mass spectrometry. Measures molecular mass to confirm the identity of the compound against its expected value.
FOR LABORATORY RESEARCH USE ONLY.
NOT FOR HUMAN OR VETERINARY USE.
