室温离子液体,又称离子液体,是一种在室温及接近室温的环境中完全以离子状态存在的液态物质.由于其具有不可燃、蒸汽压极低、黏度大、导电性和溶解能力好、高温稳定等特点,已被广泛应用于有机合成、催化、电化学、分析化学等领域.本文侧重介绍离子液体在样品预处理、毛细管电泳、高效液相色谱、气相色谱、质谱等分离领域的最新研究进展,并对其发展方向进行了展望.
Room temperature ionic liquid, also known as ionic liquid, is a kind of liquid material completely ionized at room temperature and near room temperature.Because of its non-flammable, low vapor pressure, high viscosity, good conductivity and dissolving ability, High temperature stability and other characteristics, has been widely used in organic synthesis, catalysis, electrochemical, analytical chemistry and other fields.This article focuses on the latest in ionic liquids in the field of sample pretreatment, capillary electrophoresis, high performance liquid chromatography, gas chromatography, mass spectrometry and other separation Research progress, and prospects of its development.
