Containers & Handling

  • Use clean glass or metal containers; avoid reactive plastics.
  • Minimise headspace and seal immediately to limit moisture pickup.
  • Label with batch ID, feedstock type, and sampler details.

Transport & Logistics

  • Ship samples promptly; keep cool and dark.
  • Include process notes (catalyst, wash steps) to aid interpretation.
  • Samples recorded on receipt and stored per technical requirements.

Quality & Reporting

Reports from our laboratory testing include a Certificate of Analysis (COA) with method references, results, and measurement uncertainty where applicable. We provide detailed Biofuel Testing documentation for regulatory submissions.

  • ✓ COA with analyst signature and technical authorized signatory.
  • ✓ Rapid sample intake for Houston and Gulf Coast operations.
  • ✓ Secure PDF Delivery via client portal.
  • ✓ Professional consultation for off-spec result remediation.

Frequently Asked Questions

What if my sample is off-spec?
If results from our laboratory testing fall outside technical limits, our chemists provide immediate consultation to help identify root causes (e.g., residual catalyst or moisture ingress) and advise on potential corrective blending or treatment options.
Is your laboratory ISO accredited for these methods?
Yes, AGT Labs provides accredited testing programs. Our PJLA ISO/IEC 17025 scope includes EN 14110 (methanol in biodiesel), ASTM D4176, ASTM D130, ASTM D2624, ASTM D5002, ASTM D6045 and ASTM D1218.
How fast can I get results?
Routine production QC analysis via our laboratory is typically delivered within 24 to 72 hours. We offer expedited services for Houston-area port logistics and refinery operations.
Can you quantify residual methanol?
Yes, we use accredited EN 14110 GC-FID methodology within our analytical workflows to quantify residual methanol, which is a critical safety and quality parameter for biodiesel.
