GC Grade Solvents: Product Description, Uses, and Technical Data
Product Description
GC Grade Solvents are high-purity solvents specifically designed for use in gas chromatography (GC) applications. These solvents are essential for the preparation of samples and the cleaning of equipment, ensuring accurate and reliable results in analytical chemistry. The solvents are characterized by their low levels of impurities, which can interfere with the detection and quantification of analytes. Common GC grade solvents include methanol, acetonitrile, and hexane, among others.
Uses
- Sample Preparation: Used to dissolve or dilute samples before analysis.
- Mobile Phase: Acts as a carrier for analytes in gas chromatography.
- Cleaning Agent: Used to clean glassware and instruments to prevent contamination.
- Calibration Standards: Serves as a solvent for preparing calibration standards in quantitative analysis.
- Extraction: Utilized in the extraction of compounds from various matrices.
