Analysis of Complex Petrochemicals by GC×GC–TOF MS with Select-eV Variable-Energy Electron Ionization
28 May 2014This application note shows that BenchTOF instruments, coupled with GC×GC, can provide a high-performance solution for the characterization of hydrocarbons in complex petrochemical samples. Variable-energy electron ionization technology is also shown to enhance analyte speciation by providing additional data on both molecular ions and structurally significant fragments in the low-energy mass spectra. The enhanced sensitivity and selectivity stemming from the dramatic reduction in fragmentation at low energies also greatly increases the number of compounds identified, permitting robust statistical comparisons essential for successful chemical fingerprinting.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.
