Benzene in Hexane and 1-Hexene Analysis System Nexis GC-2030BZ GC-2014BZ
Applications | 2017 | ShimadzuInstrumentation
Benzene is a toxic and regulated compound commonly found in petrochemical streams. Accurate quantification of benzene in hydrocarbon matrices such as hexane and 1-hexene is critical for ensuring product safety, regulatory compliance, and quality control in chemical manufacturing. Rapid and reliable analysis supports process optimization and environmental monitoring.
The system described here aims to provide a robust method for determining benzene concentrations between 1 ppm and 1000 ppm in hexane and 1-hexene. The analytical workflow integrates direct injection, efficient separation, and flame ionization detection to deliver fast and reproducible results.
The analytical method involves direct sample introduction via an AOC-20i autosampler into a gas chromatograph equipped with a nonpolar DB-1 capillary column. Baseline separation of benzene from matrix components is achieved, and the detector response is recorded by a flame ionization detector (FID). Quantification is performed using calibration standards, and the system software calculates benzene content along with BTU and specific gravity values.
The system delivers complete benzene analysis in approximately 7 minutes. Linearity is demonstrated across the 1–1000 ppm range, with detection limits depending on sample matrix. The method exhibits high repeatability, making it suitable for routine quality control. Typical chromatograms show clear peak resolution and an excellent signal-to-noise ratio.
Ongoing developments in gas chromatography may include multi-component BTEX analysis, enhanced detector technologies such as mass spectrometry coupling, miniaturized systems for on-site monitoring, and further automation for continuous process control.
The Nexis GC-2030BZ/GC-2014BZ system with FID detection and LabSolutions software provides a rapid, accurate, and repeatable method for benzene quantification in hexane and 1-hexene. Its ease of use and comprehensive software suite make it an effective solution for petrochemical quality control and regulatory compliance.
