Peptide purity
Assess peptide purity using an agreed chromatographic method, with the method, sample and lot clearly documented.
Analytical method
Reversed-phase HPLC with UV detection; chromatographic purity and related findings are reported under the agreed conditions.
Sample requirements
Reference quantity: 5–10 mg per sample; the final amount is confirmed in the testing plan. Lyophilized or solid powders are accepted; solutions require prior review. Provide the name, lot, form, sequence and modifications if available, storage history and testing objective. Use sealed, leak-resistant packaging that prevents contamination. Transport conditions depend on sample stability. Contact our team before shipping to confirm acceptance and transport requirements.
Turnaround
Typically 5–7 working days, starting on the working day after receipt, sample review and agreement of the testing plan. Complex projects may take longer. Shipping, customs, public holidays and time awaiting information are excluded.
Reports & deliverables
A reviewed PDF certificate of analysis (COA). Inclusion of chromatograms, spectra or raw data is agreed in the testing plan.
