Frequently Asked Questions

Why is sulfur speciation (ASTM D5623) important?
Many performance additives are sulfur-based. In our Petroleum Additive Testing Services, ASTM D5623 identifies specific sulfur species to ensure the active components are present at the correct concentration and no unwanted sulfur impurities were introduced.
Are your Ethanol testing services accredited?
Yes, our laboratory holds ISO/IEC 17025 accreditation specifically for testing Ethanol content (ASTM D5501), among other analytical methodologies.
Do you test chemical intermediates like MEG and DEG?
Yes, we provide high-resolution purity profiling and contaminant detection for essential chemical intermediates including Diethylene Glycol (DEG) and Monoethylene Glycol (MEG) to support downstream petrochemical operations.
Can you verify the purity of metal deactivators?
Yes, through our Petroleum Additive Testing Services, we use a combination of refractive index (ASTM D1218), density, and gas chromatography to verify the chemical signature and purity levels of metal deactivators and antioxidants.
How fast can I get technical COAs?
Routine profiling via our Petroleum Additive Testing Services typically takes 48 to 72 hours. We offer expedited rush services for Houston-area blending terminals and high-throughput refinery operations.
Do you test for residual solvents in additives?
