General description

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.

Application


  • Spectral Investigations of Fluorescence Tracers in Automotive and Aviation Fuels under Cryogenic Conditions: This research highlights the use of isooctane in studying the behavior of fuels at low temperatures, proving essential for improving fuel performance and safety in automotive and aviation industries (Koegl et al., 2024).

  • Versatile Application of TiO2@PDA Modified Filter Paper for Oily Wastewater Treatment: Demonstrates isooctane′s role in assessing the efficiency of innovative materials designed for environmental applications, specifically in the treatment of oily wastewaters, enhancing sustainability in industrial practices (Zhao et al., 2023).

  • Characterization and Pilot-Scale Application of the ZMS-2 Serine Protease with Novel Properties for the Eco-friendly Leather Processing: Utilizes isooctane in extracting and characterizing enzymes that significantly reduce the environmental impact of leather processing, marking a step forward in sustainable industrial manufacturing (Khan et al., 2023).

  • Rapid Construction of Caffeic Acid/p-Phenylenediamine Antifouling Hydrophilic Coating on a PVDF Membrane for Emulsion Separation: Investigates the role of isooctane in creating advanced coating solutions that improve the efficiency and longevity of separation processes, critical for environmental engineering (Tong et al., 2023).
