General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Heptane is an environmentally preferable solvent compared to hexane and thus align with "Safer Solvents and Auxiliaries". Click here for more information.
n-Heptane is a hydrocarbon liquid commonly usedas a nonpolar mobile phase or solvent in gas chromatography (GC) and reversed-phase liquid chromatography (RPLC).

Application


  • Identification of Different Classes of VOCs Based on Optical Emission Spectra Using a Dielectric Barrier Helium Plasma Coupled with a Mini Spectrometer.: This paper describes a novel analytical technique for identifying volatile organic compounds, including n-heptane, demonstrating the versatility of plasma spectroscopy in chemical analysis (Mao et al., 2024).

  • Rapid online analysis of n-alkanes in gaseous streams via APCI mass spectrometry.: This research discusses a rapid analytical method for detecting n-alkanes like n-heptane in gaseous streams, showcasing advancements in mass spectrometry for real-time environmental monitoring (Wentrup et al., 2024).
