Peptide & Nutraceutical Testing for Research Laboratories

Independent purity, identity, and contaminant analysis for academic labs, CROs, and biotech R&D — with raw data delivery, custom methods, and volume pricing.

At a Glance

What peptide testing do research laboratories most commonly need?

Research laboratories typically order HPLC purity testing to confirm at least 95% peptide purity, mass spectrometry for identity verification and modification detection, and contaminant screening (heavy metals, residual solvents, endotoxins) for in vivo work. Cert Biohealth Testing Labs offers all of this from our Toronto laboratory, with electronic Certificates of Analysis in 9–11 business days and support for method development for novel sequences.

What Research Labs Get from Us

HPLC Purity

Reverse-phase HPLC at 214 nm and 220 nm with complete chromatograms and main peak integration.

Mass Spectrometry Identity

ESI-MS and LC-MS/MS for sequence confirmation, molecular weight verification, and modification detection.

Custom Method Development

ICH Q2(R1) method design and validation for novel sequences, conjugates, and lipopeptides.

Raw Data Delivery

Receive raw instrument files (.raw / .d / mzML) alongside your signed COA for independent reanalysis or supplementary data.

Publication Support

Method descriptions ready for Materials & Methods sections and supplementary data tables for peer-reviewed journals.

Academic Pricing

Discounted rates for university laboratories, research grant accounts, and ongoing CRO programs.

Common Research Workflows We Support

• QC of newly synthesized peptides before experiment start
• Batch-to-batch consistency testing for in vivo studies
• Post-storage stability follow-up after accelerated conditions
• Endotoxin and heavy metal clearance for animal work
• Independent verification before publication or data submission
• Method transfer for in-house QC implementation

FAQ for Research Laboratories

Do you offer academic or CRO pricing?

Yes. Academic institutions and non-profit research organizations qualify for discounted rates on standard testing panels. CROs with monthly testing volume also benefit from preferred pricing. Contact us with your affiliation and expected volume for a custom quote.

Can you develop a custom HPLC or MS method for an unusual peptide?

Yes. We develop HPLC and MS methods for novel sequences, cyclic peptides, PEGylated conjugates, lipopeptides, and other non-standard structures. Provide us with your sequence and any available reference data, and we will scope the method development project for you.

What sample size is needed for research peptide testing?

Minimum 100–500 µg for HPLC purity alone, 0.5–2 mg for identity confirmation, and 1–5 mg if endotoxin testing is also required. If your material is limited, contact us before shipping so we can prioritize tests appropriately.

Do you provide raw chromatogram and spectrum data files?

Yes. Raw data files (.raw, .d, mzML) are available for all HPLC and MS analyses at no additional charge. Simply request them on your submission form. These are commonly required for supplementary data in peer-reviewed publications.

Can you support a publication or grant application?

Yes. We provide method descriptions in the format required for Materials & Methods sections, can write method summaries for supplementary data, and can provide a letter confirming our laboratory accreditation status upon request for grant applications.
