From order to report

1. Order and intake

Add tests to your cart, then complete the intake form: who you are, one entry per sample, the tests each sample needs, and how you want results reported. We email an invoice; payment is due in full before testing starts. You receive a submission number (TPR-S-…) and a printable sample submission form.

2. Label and pack

• Label every container with the sample ID you entered at intake and the submission number. Use a solvent-resistant label or marker.
• Send at least the amount listed for each test, in a sealed primary container inside a leak-proof secondary bag with absorbent material for liquids.
• Put the printed, signed sample submission form in the box, outside the secondary bag.

3. Ship

• Ship Monday to Wednesday so samples do not sit in transit over a weekend.
• Refrigerated samples: insulated shipper with frozen gel packs. Frozen samples: dry ice, labeled to carrier rules.
• We send the shipping address for samples with your quote or invoice.

4. Receipt and acceptance

On arrival we check each container against your order. If something does not match (a missing label, a broken seal, too little material) we contact you before testing.

5. Testing and review

Average turnaround is 14 to 31 days. Results are verified, including any work done by a partner laboratory, and the certificate of analysis is signed off before release.

6. Certificate of analysis and leftover sample

The certificate of analysis gives your results with the chromatogram and spectra. Leftover sample is destroyed, or returned to you at your expense if you ask for it when you order. We invoice return shipping before we ship.
