Hexane Testing — Grade, Purity & Compositional Confidence
AGT Labs delivers ISO/IEC 17025-accredited hexane testing focused on the appearance, purity and hydrocarbon composition of hexane. Our services use recognized ASTM and chromatographic methods to confirm grade, detect hydrocarbon impurities and provide defensible data for QC and acceptance decisions.
We concentrate on the parameters your specification requires — color, odor, carbon residue, non-volatile residues, refractive index and detailed hydrocarbon profiling by GC-FID. Reports are concise, accredited and tailored to industrial acceptance criteria.
Typical clients: extractors, solvent suppliers, chemical processors, formulators and QA laboratories.
Service Highlights
- Grade and appearance checks (ASTM color, visual odor) for batch acceptance.
- Compositional profiling using GC-FID (hydrocarbon distribution / DHA) to confirm n-hexane content and detect light/heavy impurities.
- Residue and stability screens (carbon residue, non-volatile matter, refractive index) with clear COA language for acceptance decisions.
Industries We Serve
- Food & Botanical Extraction — appearance and composition checks for solvent suitability.
- Pharmaceuticals — identity and purity confirmation for process solvents.
- Solvent Suppliers & Distributors — incoming QC and batch verification.
- Polymer & Chemical Manufacturing — solvent consistency and contamination screening.
- Quality Labs — routine characterization and cross-check testing.

Laboratory Capabilities & Instrumentation
Analytical Systems
Appearance, corrosivity, residue and nonvolatile matter assessments, refractive index, conductivity, and compositional analysis using ASTM methods D2163, D5623 and D8150 to evaluate identity, purity and contamination.
Quality & Traceability
- Calibration with traceable reference materials and documented procedures.
- COA includes method references, results and observations relevant to quality.
- Chain-of-custody and documented handling available for contract testing.
Sampling, Handling & Chain of Custody
Representative sampling is essential for accurate solvent testing. Use clean containers, avoid cross-contamination, and provide all relevant batch details. Chain-of-custody documentation ensures full traceability from receipt to reporting.
Containers & Handling
- Use clean amber glass or certified metal containers; keep tightly sealed.
- Minimize headspace to maintain integrity for volatile components.
- Label with sample ID, batch, sampling point, date and handler details.
Transport & Documentation
- Ship at ambient conditions unless otherwise specified.
- Include product history or handling notes for troubleshooting.
- Chain-of-custody forms required for witnessed or contractual testing.
Refer to our Sample Submission Guide for packing and documentation instructions.
Quality Assurance, Reporting & Interpretation
Certificates of Analysis include method references, quantitative results, observations and, where applicable, measurement uncertainty. Off-spec findings are supported with interpretive notes and follow-up recommendations.
Turnaround Times & Test Packages
| Package | Typical Tests | Typical TAT |
|---|---|---|
| Purity Panel | Color, odor, refractive index, hydrocarbon composition | 24–48 h |
