HPLC / UHPLC purity testing
HPLC/UHPLC separates related substances and process impurities, with PDA/UV-Vis detection at 220 nm used to assess main-peak purity.
B2B bulk analytical testing
Independent Testing
Clear Purity Results
Third-party purity and identity testing for research peptide vendors, with a certificate of analysis for each sample.
COA verification
Verify a Certum Labs COA
Confirm an issued certificate with its verification code, or contact the lab with the accession number and company name.
Services
Bulk testing for research providers
We work with suppliers, brands, and research organizations on bulk analytical programs. Scope and methods are confirmed during intake.
Identity testing
Assess peptide identity using mass spectrometry. Sequence-related analysis is confirmed during intake.
Additional testing on request
Quantity or content analysis and other assays may be available depending on sample type. Scope is confirmed before work begins.
Process
How testing works
Inquire about your program
Share compounds, approximate volume, requested tests, and timing. We confirm whether the work fits a bulk B2B testing engagement.
Confirm scope and logistics
After intake approval, we lock testing scope and provide packing and shipping instructions. Do not ship until confirmed.
Receive certificates of analysis
We analyze approved lots and issue COAs for your quality documentation.
Certum Labs is B2B bulk testing for research providers — not a consumer sample drop-off.
About
Independent testing for research providers
Certum Labs provides third-party analytical testing and certificates of analysis for research suppliers, brands, and organizations running bulk quality programs. Testing scope is agreed before analysis so your documentation reflects the work performed.
