The chiral compounds may be biomarker candidates in human metabolism, which indicates the health status of humans. There are many applications in LC/MS that show that chiral small molecules are promising biomarkers for human diseases. Both clinical and commercial analyses of chiral metabolites are necessary due to the enantiomeric ratios of chiral molecules in biological samples may show both human health status and diseases. This review provides current and advanced LC/MS techniques for the separation and analysis of chiral molecules as disease biomarkers. In particular, sample preparation and chromatographic analysis of potential chiral biomarkers in biological samples are presented. The preparation and applications of several chiral columns used in enantiomeric separation of chiral metabolites/biomarkers by advanced LC/MS techniques are discussed. The improvement of these analyses will enable both the discovery of new chiral biomarkers and the prognosis of human diseases.

Phenylpyrazoles are widely used pesticides in the food industry. It is highly desirable to develop efficient pre‐treatment and analysis methods to extract and detect phenylpyrazoles in complex food matrices. Herein, the study reports novel squaraine‐linked zwitterionic core‐shell magnetic covalent organic frameworks (MCOFs), which are found to be excellent pretreatment materials for the detection of trace phenylpyrazoles in samples. By coupling MCOFs to magnetic solid‐phase extraction (MSPE) with Ultra Performance Liquid Chromatography‐Tandem Mass Spectrometry (UPLC‐MS/MS) analysis, the detection of phenylpyrazoles (fipronil, fipronil sulfone, fipronil sulfide, fipronil de‐sulfoxide, fipronil desulfinyl, ethiprole, and flufiprole) is achieved and shows good linearity at concentrations of 1–800 µg L−1 (R2 ≥ 0.9930). The limit of detection (LOD), limit of quantification (LOQ), and recovery rates are 0.01–0.50 µg kg−1, 0.04‐1.72 µg kg−1, and 70.96–115.32%, respectively. More importantly, this method is successfully applied to determine the phenylpyrazoles in commercial egg, poultry, milk, jujube, cabbage, tea, and rice with a detection rate of ≈0.04%. Therefore, the developed method may contribute to a new strategy for the purification and multi‐target extraction of complex food matrices.
