Description

Eicosylbenzene Standard For GC is a high-purity, well-defined chemical reference material used for the calibration and qualification of analytical instruments. This compound is critical for ensuring the accuracy, precision, and reliability of gas chromatography (GC) analyses in research and quality control laboratories. It is an essential standard for scientists and technicians in the petrochemical, pharmaceutical, environmental testing, and specialty chemical industries who require definitive benchmarks for method validation and system suitability testing.

Application

• Primary Standard for Gas Chromatography (GC): Used for calibrating retention times, calculating Kovats indices, and verifying column performance.
• Method Development and Validation: Serves as a critical component in establishing and validating new GC analytical methods for complex mixtures.
• Quality Control in Petrochemical Analysis: Employed as a reference standard for the identification and quantification of high molecular weight hydrocarbons and aromatic compounds.
• System Suitability Testing: Ensures that the entire GC system (injector, column, detector) is operating within specified parameters before sample analysis.
• Research and Reference Material: Used in academic and industrial research laboratories studying long-chain alkylbenzene chemistry, surfactants, or polymer additives.
• Environmental Testing: Can be utilized as a standard in methods designed to detect and measure persistent organic pollutants or hydrocarbon contaminants.
