Standard peptide analysis: 5-10 business days after receipt and acceptance. Timing for other methods is confirmed in the quote.
How this analysis works
HPLC peptide purity testing estimates the proportion of detected chromatographic signal assigned to the principal peak. It is run by HPLC with ultraviolet detection on every accepted sample, costs $280 CAD per sample and includes identity confirmation; volume rates fall to $225 CAD at twelve or more samples.
Area purity is not the same as peptide content or milligrams per vial.
Co-eluting compounds may not be resolved by one method.
The result applies only to the sample received.
What to submit
Lyophilized powder or another pre-approved matrix
Provide the expected compound and nominal amount when known
Final sample quantity confirmed after feasibility review
Reading the result
Read the area-purity percentage with the chromatogram, detector wavelength and integration basis. The percentage describes the detected response assigned to the target peak under those conditions.
HPLC Peptide Purity Testing starts at $280 CAD per accepted sample, excluding tax and shipping. Scope and the final price are confirmed before you mail anything. Volume rates apply from three samples carrying this test in one request.
02
How long does this test take?
Target turnaround is 5 to 10 business days from the day the laboratory receives an accepted sample. Two-business-day rush is $199 CAD per sample, subject to capacity and method readiness, from receipt and acceptance.
03
Does HPLC purity tell me how many milligrams are in the vial?
No. Area purity and peptide content are different measurements. Request content measurement if the labelled vial amount is the question you need answered.
04
Is a high-purity result proof of identity?
No. A dominant peak alone does not establish which material produced it. The peptide panel includes a separate identity assessment; the report states the techniques used.
05
Can two compounds appear as one HPLC peak?
Yes. Separation depends on the compounds and method conditions. Where co-elution prevents the requested conclusion, further method work or a different analytical technique may be needed.
