Ionic liquids (ILs) are non-molecular solvents, which are mainly characterized as possessing low melting points, low-to-negligible vapor pressures, and high thermal stability. Their unique solvation properties, coupled to the fact that they can be structurally tailored for specific applications, have increased study of ILs in many areas of fundamental and applied chemistry. Thus, ILs have successfully been utilized as novel solvents in different extraction and microextraction schemes in recent years, but mainly with environmental samples.Food samples are quite complicated matrices from an analytical point of view. They contain a large range of chemical substances, and sometimes they also have a...

Yong-Liang, Yu , Ying, Jiang , Ming-Li, Chen , Jian-Hua, Wang
In the past decade, the lab-on-valve (LOV) system, as the third-generation of the flow-injection (FI) analysis technique, has exhibited powerful capability in instrument miniaturization and on-line sample pretreatment.This review presents and discusses the state of the art in the progress of the LOV system in the determination of metal species in two parts:miniaturization of analytical instrumentation; and,sample-processing front-ends.As a miniaturized analytical set-up, LOV incorporates detection techniques for the determination of metal species (e.g., spectrophotometry, electrochemical detection and atomic spectrometry). However, coupling LOV sample pretreatment with atomic or mass spectrometric detectors provides high-sensitivity determination or speciation of metal species.We also discuss...
