“…To obtain the highest extraction efficiency, the effects of different solvents (ethanol, methanol, acetonitrile, dichloromethane, isopropanol, and n-hexane), auxiliary extraction methods (ultrasound and shaker), extraction times (20,25,30,35, and 40 min), solvent volumes (10,15,20,25, and 30 mL), extraction temperatures (20,30,40,50…”

“…The single-factor optimization experiment has been widely used to optimize extraction conditions to obtain the highest extraction efficiency (23,24). The single-factor experiment is easy to operate, but the disadvantage is that it cannot reflect the influence of the interaction between the variables on the extraction efficiency (25). Fortunately, OED can be used to overcome these drawbacks.…”

Monitoring the characteristic components in tipping paper is important to ensure the quality of cigarette products. This study establishes a method based on gas chromatography (GC) for determining cooling agents in tipping paper. The tipping paper was cut into pieces and extracted by ethanol under specific temperatures in a shaker. Then, the characteristic cooling agents of (-)-menthone, L-menthol, and (-)-menthyl lactate in extract were determined using GC coupled with a flame ionization detector (GC-FID). The limits of detection (LODs) and limits of quantification (LOQs) for the three cooling agents ranged from 0.15~0.32 μg/mL and 0.49~1.06 μg/mL, respectively. Results demonstrated a good linear relationship with high correlation coefficients for the three tested cooling agents. The extraction conditions of the cooling agents were optimized through a single-factor experiment as well as an orthogonal experiment. The standard addition recovery experiment showed that the average recoveries range from 81.23 to 100.62%, and the relative standard deviations (RSDs) of the measured values (n = 5) ranged from 0.34 to 1.64%.

“…When graphene-based sheets are bonded to Si particles, the covalent bond prevents the accumulation of free graphene-based sheets and avoids blocking. For example, GO sheets covalently bonded to Si particles (SiGO) and modified with β-CD were packed in a cartridge and used for the extraction and analysis of polycyclic aromatic hydrocarbons (PAHs) from fried food [ 55 ]. This strategy resulted in an LOD range of 0.1–0.3 μg·L −1 and a recovery range from about 55 to 90%.…”

This review provides an overview of recent advancements in applying graphene-based materials as sorbents for liquid chromatography (LC) analysis. Graphene-based materials are promising for analytical chemistry, including applications as sorbents in liquid chromatography. These sorbents can be functionalized to produce unique extraction or stationary phases. Additionally, graphene-based sorbents can be supported in various materials and have consequently been applied to produce various devices for sample preparation. Graphene-based sorbents are employed in diverse applications, including food and environmental LC analysis. This review summarizes the application of graphene-based materials in food and environmental water analysis in the last five years (2019 to 2023). Offline and online sample preparation methods, such as dispersive solid phase microextraction, stir bar sorptive extraction, pipette tip solid phase extraction, in-tube solid-phase microextraction, and others, are reviewed. The review also summarizes the application of the columns produced with graphene-based materials in separating food and water components and contaminants. Graphene-based materials have been reported as stationary phases for LC columns. Graphene-based stationary phases have been reported in packed, monolithic, and open tubular columns and have been used in LC and capillary electrochromatography modes.

“…Graphene-based phases can be present in different ways. Fe 3 O 4 magnetic particles containing graphene [ 4 ] or graphene oxide [ 5 ], graphene-based aerogels [ 6 , 7 ] and hydrogels [ 8 , 9 ], and graphene-based material fixed on silica particles [ 10 , 11 , 12 ] are examples of how these materials can be produced. Other possibilities of application for graphene-based materials are summarized in recent reviews [ 13 , 14 , 15 ].…”

“…Applications in separation science are as diverse as the possibilities of graphene-based material compositions [ 16 , 17 , 18 ]. Techniques such as stir bar sorptive extraction [ 16 , 19 ], solid-phase extraction [ 10 , 20 ], fiber solid-phase microextraction [ 20 , 21 ], in-tube solid-phase microextraction [ 12 , 22 ], and others [ 1 , 23 , 24 ] are examples of graphene-based material applications in sample preparation techniques. A particular focus can be given to column-switching methods coupled with LC or miniaturized LC because they minimize the steps of sample preparation procedures [ 25 , 26 ].…”

Graphene oxide sheets fixed over silica particles (SiGO) and their modification functionalized with C18 and endcapped (SiGO-C18ec) have been reported as sorbents for extraction and analytical columns in LC. In this study, a SiGO column was selected as the extraction column and a SiGO-C18ec as the analytical column to study the applicability and limitations of a column-switching system composed exclusively of columns packed with graphene-based sorbents. Pyriproxyfen and abamectin B1a were selected as the analytes, and orange-flavored carbonated soft drinks as the matrix. The proposed system could be successfully applied to the pyriproxyfen analysis in a concentration range between 0.5 to 25 µg/mL presenting a linearity of R2 = 0.9931 and an intra-day and inter-day accuracy of 82.2–111.4% (RSD < 13.3%) and 95.5–99.8% (RSD < 12.7%), respectively. Furthermore, the matrix composition affected the area observed for the pyriproxyfen: the higher the concentration of orange juice in the soft drink, the higher the pyriproxyfen the signal observed. Additionally, the SiGO extraction column presented a life use of 120 injections for this matrix. In contrast, the proposed system could not apply to the analysis of abamectin B1a, and the SiGO-C18ec analytical column presented significant tailing compared to a similar approach with a C18 analytical column.
