荧光相关光谱（FCS）测量了三种不同电荷的荧光探针（阳离子：罗丹明6G，中性：4-二氰亚甲基-2-甲基-6-对二甲氨基苯基-4- h -吡喃，DCM和阴离子：荧光素）溶解在普通室温离子液体1-丁基-3-甲基咪唑六氟磷酸，[bmim][PF6]中的平动扩散系数。这些实验表明，FCS是一种快速、灵敏、精确（典型RSD为4-8%）、低消耗的筛选工具，可用于测定微升离子液体样品中的分析物迁移率。
Fluorescence correlation spectroscopy (FCS) measurements have been performed in order to determine the translational diffusion coefficients of three differently charged fluorescent probes (cationic: rhodamine 6G, neutral: 4-dicyanomethylene-2-methyl-6-p-dimethylaminostyryl-4-H-pyran, DCM, and anionic: fluorescein) dissolved within the common room temperature ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate, [bmim][PF6]. These experiments demonstrate that FCS is a rapid, sensitive, precise (typical RSD from 4-8%), and low-consumption screening tool for the determination of analyte mobility within microliter ionic liquid samples.
