“…The mass transfer efficiency of multiphase systems is significantly improved at high temperatures [79]. Cooling the fibers allows them to maintain good absorption in a thermal sample environment [80]. To improve the extraction efficiency and capacity of the SPME device, new geometries of the sorbent phase were used, like SPME Arrow and thin-film SPME (TF-SPME).…”

To meet consumer demand for fermented beverages with a wide range of flavors, as well as for quality assurance, it is important to characterize volatiles and their relationships with raw materials, microbial and fermentation processes, and the aging process. Sample preparation techniques coupled with comprehensive 2D gas chromatography (GC×GC) and mass spectrometry (MS) are proven techniques for the identification and quantification of various volatiles in fermented beverages. A few articles discuss the application of GC×GC for the measurement of fermented beverage volatiles and the problems faced in the experimental analysis. This review critically discusses each step of GC×GC-MS workflow in the specific context of fermented beverage volatiles’ research, including the most frequently applied volatile extraction techniques, GC×GC instrument setup, and data handling. The application of novel sampling techniques to shorten preparation times and increase analytical sensitivity is discussed. The pros and cons of thermal and flow modulators are evaluated, and emphasis is given to the use of polar-semipolar configurations to enhance detection limits. The most relevant Design of Experiment (DoE) strategies for GC×GC parameter optimization as well as data processing procedures are reported and discussed. Finally, some consideration of the current state of the art and future perspective, including the crucial role of AI and chemometrics.

“…In order to evaluate the performance of the current method, it was compared with some relevant reported methods [2,[33][34][35] in regard to the SPME fiber involved, the extraction time, desorption time, linearity, LODs, RSDs, recoveries, and the contents found in real samples for the determination of PAEs, and the relevant data are provided in Table S5. The results indicate that the extraction time of the current method (40 min) is shorter than that of MWCNTs@PS (60 min) and DVB/CAR/PDMS (60 min) [33,35], and comparable to that of the Graphene-Ti (40 min). The length of the desorption time is similar to that of the other methods.…”

A porous boron nitride with a large surface area was synthesized by a one‐step grinding method with melamine, urea, and boric acid as the precursors. The prepared porous boron nitride was used as the fiber coating material for the solid‐phase microextraction of seven phthalate esters (diethyl phthalate, diallyl phthalate, diisobutyl phthalate, dibutyl phthalate, butylbenzyl phthalate, dicyclohexyl phthalate, and di‐2‐ethylhexyl phthalate) prior to their gas chromatography‐mass spectrometric detection. The important experimental parameters including the extraction time, extraction temperature, salt concentration, and stirring rate were optimized by both single factor and central composite design methods. Under the optimized experimental conditions, the linear response range for the analytes was from 0.030 to 30.0 μg/L, and the limits of detection were from 0.010 to 0.040 μg/L, respectively. The relative recoveries of the analytes for spiked samples at two concentration levels were 83.0–109% with the relative standard deviations less than 12%. The established method was successfully applied for the determination of the phthalate esters in bottled juice beverage samples.

“…In a few reports [ [22] , [23] , [24] , [25] ], a generation of cooled SPME named cold fiber for extraction of the volatile compounds to increase the analyte distribution coefficient between the adsorbent and headspace sample was introduced. Recently, a distillation condenser, as a cooling zone, was applied to combine the headspace SPME with purge assisted [ 26 ]. The results revealed the approach of that method for more analysis of the volatile compounds with the lowest effect of the sample matrix.…”
