Product Overview

Toluene 99.9% GC-HS (CAS No. 108-88-3) is methylbenzene supplied for headspace gas-chromatographic procedures where volatile background and reproducible vapour-phase behaviour are particularly relevant. Toluene readily partitions into the headspace above condensed samples and is itself a common volatile organic analyte, making control of trace volatile impurities important when the material is used for method development, spiking or comparative headspace studies.

The GC-HS grade is intended for headspace chromatographic sample preparation, blank evaluation, calibration-related work and method development involving volatile organic compounds. It is particularly relevant to procedures in which toluene is used as a solvent component, reference compound or target analyte in headspace analysis.

Typical Applications

• Preparation of non-certified toluene working solutions for GC-HS.
• Headspace partition and equilibration studies.
• Method development for volatile organic compounds.
• Recovery and matrix-spiking investigations involving toluene.
• Headspace blank and background evaluation where method-appropriate.
• Residual-solvent and volatile-aromatic research.

Common Synonyms

• Methylbenzene
• Toluol
• Phenylmethane

Storage Conditions

Keep tightly closed to minimise evaporative concentration change and uptake of external volatile contaminants. Maintain dedicated clean GC-HS handling so that headspace background remains as reproducible as practical.
