Development of a Dispersive Liquid-Liquid Microextraction Method for Quantification of Volatile Compounds in Wines Using Gas Chromatography-Mass Spectrometry.

ABSTRACT: Background/Objectives: This study reports the development of a straightforward, efficient, and cost-effective dispersive liquid-liquid microextraction (DLLME) method for the gas chromatography-mass spectrometry (GC-MS) analysis of volatile compounds present in wine. Methods: Four critical parameters were optimised using a D-optimal design to maximise extraction outcomes of the targeted analytes from a 10 mL sample, while minimising interference from other compounds. The analytical characteristics of the method were assessed using 36 target compounds. Results: The method provided satisfactory linearity (correlation coefficients > 0.990), good repeatability for both for intra- and inter-day measurements (RSD < 10.3%), and suitable recoveries of target analytes from both
