Frequently Asked Questions
Common questions about our analytical testing services.
What is HPLC peptide analysis?
HPLC (High-Performance Liquid Chromatography) is an analytical technique used to separate, identify, and quantify components in a sample. For peptides, it evaluates purity by measuring peak profiles against the sample mixture.
How do I submit a sample?
Use our online intake form to enter your sample details, select testing options, and receive a unique sample ID with shipping instructions. Then mail your labeled sample to our laboratory.
How do I verify a COA?
Visit the COA Lookup page and enter the Sample ID or Verification Code printed on your certificate. The system will confirm the report status and display verified results.
What information is included in a report?
Reports include the sample ID, peptide name, batch/lot number, test method, purity result, chromatogram image, test and report dates, reviewer information, and a unique verification code.
How long does testing take?
Standard turnaround is typically 3-5 business days after sample receipt. Expedited processing may be available depending on service configuration.
Can vendors submit multiple samples?
Yes. Vendors and researchers can submit multiple samples and manage them through the client portal, which provides organized tracking, status updates, and report downloads.
