Product Overview

Chloroform 99.5% GC (CAS No. 67-66-3) is a volatile chlorinated solvent intended for gas-chromatographic sample preparation and solvent-background control. Its volatility permits efficient transfer through suitable GC injection systems, while its solvating properties support dilution or extraction of compatible volatile and semi-volatile organic compounds.

The GC grade is intended for preparation of samples, blanks and non-certified working mixtures where chromatographically detectable solvent impurities and non-volatile contamination must be controlled.

Typical Applications

• Dilution and preparation of compatible samples for gas-chromatographic analysis.
• Extraction of volatile and semi-volatile organic analytes before GC determination.
• Preparation of solvent blanks and procedural blanks.
• Preparation of non-certified working mixtures containing chloroform or compatible analytes.
• Evaluation of volatile impurities and solvent-related chromatographic interferences.
• GC and GC–MS method development where chloroform is a validated solvent or analyte.

Common Synonyms

• Trichloromethane
• Methane Trichloride
• Methyl Trichloride
• Trichloroform
• Chloroform

Storage Conditions

Store tightly closed and protect from direct light, excessive heat, prolonged air exposure, evaporation, moisture and chromatographic contamination. Use clean dispensing equipment to preserve volatile composition, low residue and blank cleanliness.
