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
- In-house validation of accelerated solvent extraction-gas chromatography-mass spectrometry for the determination of bound 3- and 2-monochloropropanediols (MCPD) and glycidol in food products.: This study showcases the validation of a robust analytical method, crucial for ensuring food safety and compliance with regulations. The use of isohexane in the process highlights its application in improving extraction efficiency and analysis precision (Shaari et al., 2021).
- Optimized determination of polybrominated diphenyl ethers and polychlorinated biphenyls in sheep serum by solid-phase extraction-gas chromatography-mass spectrometry.: Demonstrates the refinement of extraction and detection techniques using isohexane for environmental pollutants in biological samples, enhancing the sensitivity and accuracy of these measurements (Zhang & Rhind, 2011).
- Simultaneous extraction and clean-up of polybrominated diphenyl ethers and polychlorinated biphenyls from sheep liver tissue by selective pressurized liquid extraction and analysis by gas chromatography-mass spectrometry.: This article describes a streamlined method to simultaneously extract and purify specific contaminants from liver tissue, with isohexane playing a critical role in the efficiency of the extraction process (Zhang et al., 2011).
- Selective pressurized liquid extraction of estrogenic compounds in soil and analysis by gas chromatography-mass spectrometry.: Focuses on the targeted extraction of hormone disruptors from environmental samples, where isohexane′s selective solvation properties are utilized to enhance the selectivity and yield of the analytes (Zhang et al., 2011).
- Fast sample preparation involving MASE and coupled column normal phase liquid chromatography for the rapid trace analysis of dioxins in air-dust samples from fire catastrophe emissions.: Discusses a rapid preparation and analysis method for trace contaminants in complex matrices, underscoring isohexane′s role in achieving fast and reliable results (van Beuzekom et al., 2004).
