Xylene Testing Services & Isomer Analysis

Providing accredited Xylene Testing Services for isomer distribution, Nitration Grade (ASTM D843), and Ten-Degree Xylene purity.

High-Purity Aromatic Solvent Verification

Xylene is a complex aromatic solvent consisting of three isomers (ortho-, meta-, and para-xylene) alongside ethylbenzene. AGT Labs provides professional Xylene Testing Services to accurately resolve and quantify these components using high-resolution Gas Chromatography. We verify purity against strict standards like ASTM D843 (Nitration Grade) and ASTM D846 (Ten-Degree Xylene).

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 ensures your feedstock is free of harmful non-aromatics and trace sulfur.

Value for Stakeholders: Chemical Manufacturers ensuring feedstock purity through our Xylene Testing Services, Paint Formulators verifying solvent quality, and Plastics Producers confirming para-xylene concentration.

Frequently Asked Questions

Why is isomer distribution (ortho, meta, para) important?
Different xylene isomers serve entirely different markets. For example, para-xylene is essential for making PET plastics, while ortho-xylene is used for phthalic anhydride. Precise GC testing ensures the right isomer balance.
Why test for ethylbenzene in xylene?
Ethylbenzene naturally occurs with mixed xylenes and boils at a very similar temperature, making it hard to separate. We quantify it because high ethylbenzene levels can negatively impact downstream chemical synthesis.
What is Ten-Degree Xylene (ASTM D846)?
Ten-Degree Xylene is a commercial grade defined by its boiling range. It must completely distill within a 10°C range, indicating a specific purity level suitable for industrial solvent applications.
How do you separate xylene isomers in the lab?
Meta-xylene and para-xylene have nearly identical boiling points. We utilize specialized high-resolution capillary columns in our Gas Chromatographs (per ASTM D7504) to successfully resolve and measure each isomer accurately.
