一般描述
LiChrosolv 溶剂具有较高的紫外线透射率、低颗粒数、低酸碱度和低蒸发残留量，因而其是可重现分离的理想选择。由于在分析型HPLC中分离通常在梯度条件下进行，因此我们提供“梯度级”和“等度级”的溶剂。这使得所使用的溶剂的梯度影响最小化。
应用
- 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).
