| Assay method | HPLC column, gradient, wavelength, integration rules | Make two quotations comparable |
| Water & solvents | Method and limit stated on the batch COA | Know the mass you actually weigh |
| Batch traceability | COA batch number matches the pack label | Pre-clear the shipment at QA release |
| Document list | Listed in the quotation before sampling | Avoid chasing reports at goods receipt |

Technical Notes
What is confirmed before a sample ships
We treat the catalogue as a starting point for a technical conversation, not as a set of binding release limits. The identity, the analytical method and the document list are agreed with the buyer before any sample is dispatched.
Which identifiers should a buyer verify first
Start with the registry number, the sequence and the molecular weight, then ask which analytical method produced the reported value. Two quotations are only comparable when both name the same method and the same basis of calculation.
How do we handle documents
Tell us which reports your destination market requires. We list them in the quotation rather than leaving them to be chased at goods receipt.
What happens after sample approval
Once a sample is approved, the same specification and the same analytical method should be kept for subsequent commercial batches so that results stay comparable.
