AGT Labs Petroleum Testing

Xylene Testing Services & Quality Analysis

ISO/IEC 17025 accredited xylene testing in Houston, TX for mixed xylenes and xylene isomers, with samples accepted nationwide.

Accredited Aromatic Solvent Testing

Xylene is a complex aromatic solvent consisting of three isomers (ortho-, meta-, and para-xylene) alongside ethylbenzene. AGT Labs provides Xylene Testing Services using ISO/IEC 17025 accredited methods for copper corrosion by industrial aromatic hydrocarbons (ASTM D849), color, acidity, nonvolatile matter, sulfur compounds, refractive index and odor.

Our analysis supports chemical plants, plastics manufacturers, and solvent blenders. Whether you require pure p-Xylene for Terephthalic Acid (PTA) production or mixed xylenes for industrial coatings, our accredited data helps confirm your feedstock is free of corrosive sulfur and contamination.

Frequently Asked Questions

Which xylene tests are accredited at AGT Labs?
Our PJLA ISO/IEC 17025 scope covers copper strip corrosion by industrial aromatic hydrocarbons (ASTM D849), color on the Pt-Co scale (ASTM D1209), acidity (ASTM D1613), nonvolatile matter (ASTM D1353), sulfur compounds by GC-PFPD (ASTM D5623), refractive index (ASTM D1218) and odor (ASTM D1296).
Why test copper corrosion in xylene?
ASTM D849 is designed for industrial aromatic hydrocarbons and shows whether xylene contains corrosive sulfur that could attack copper and copper alloys in equipment.
How fast can I get xylene results?
Routine analysis is typically available within 24 to 48 hours. We offer expedited rush services for urgent cargo transfers and production needs.
