- Obtain the domestic receiving instructions directly from us.
- Agree a clear sample reference and retain your supplier / order reference.

When you receive the report.
Review the English PDF report alongside your supplier documentation and order requirements. Check that sample references and methods support the comparison you want to make.
Seek clarification if a finding is unclear. You decide whether to authorize shipment under your supplier agreement. We do not manage supplier payments or international shipping.
For multiple samples, confirm identification and reporting arrangements before dispatch.
Know exactly what
your report represents.
Independent evidence is useful when its
boundaries are understood.
What the test can tell you
- Analytical findings for the sample received
- HPLC purity information
- MS identity / molecular weight information
What the test cannot tell you
- Whether the submitted sample represents every vial
- Whether it represents the entire batch
- Whether a later shipment is identical to the tested sample
Test results apply only to the sample received and tested. Results do not certify or guarantee the entire batch or shipment.
