Application of Liquid- and Supercritical Fluid Chromatography Coupled with High-Resolution Mass Spectrometry for the Analysis of Short-, Medium-, and Long-Chain Chlorinated Paraffins in Dietary Supplements

Scientists used supercritical fluid chromatography (SFC) and ultrahigh-pressure liquid chromatography (UHPLC)—both coupled with high-resolution mass spectrometry (HRMS)—to analyze various types of chlorinated paraffins (CPs) in fish oil-based dietary supplements.

Application of Liquid- and SFC Coupled with HRMS for the Analysis of Short-, Medium-, and Long-Chain Chlorinated Paraffins in Dietary Supplements

This article presents SFC and UHPLC—both coupled with HRMS—methods for the analysis of short-, medium-, and long-chain CPs in fish oil-based dietary supplements.

Application of Liquid- and Supercritical Fluid Chromatography Coupled with High-Resolution Mass Spectrometry for the Analysis of Short-, Medium-, and Long-Chain Chlorinated Paraffins in Dietary Supplements

In this study, SFC and UHPLC—both coupled with HRMS—methods for the analysis of short-, medium-, and long-chain CPs in fish oil-based dietary supplements were developed and validated at concentration levels of 0.6 and 3.0 µg/g lipid weight (lw).

Authentication of Panax Ginseng‑Based Herbal Teas Using “Chemical Markers” Strategy

This article describes the method development involved in the authentication of nutraceuticals, particularly those containing Panax ginseng, which is popular because of possible positive effects on human health.

Analysis of UV-Treated Mushrooms: Dietary Source of Vitamin D2?

In our study, a fast and sensitive liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) method for the determination of vitamin D2 in fresh mushrooms and its metabolite 25(OH)D2 in the blood of volunteers regularly consuming UV-treated mushrooms has been introduced.

Analysis of MCPD and Glycidyl Fatty Acid Esters in Refined Plant Oils by Supercritical Fluid Chromatography– High-Resolution Mass Spectrometry

The aim of this study was to develop an efficient method to enable a rapid determination of nine 3-MCPDEs and seven GEs in vegetable oils within a single run employing supercritical fluid chromatography coupled to high-resolution tandem mass spectrometry (SFC–HRMS/MS).
