“…Plants are complex matrixes because of their pigments and other possible interferences to their analysis, so a sample preparation procedure before the instrumental analysis is necessary. As sample preparation is the step with major environmental impact in the analysis, the trend in the last decades has been to develop fast and simple methodologies with minimized sample, solvent, and reagents consumption .…”

A simple method for the simultaneous determination of personal care product ingredients: galaxolide, tonalide, oxybenzone, 4-methylbenzyliden camphor, padimate-o, 2-ethylhexyl methoxycinnamate, octocrylene, triclosan, and methyl triclosan in lettuce by ultrasound-assisted extraction combined with solid-phase microextraction followed by gas chromatography with mass spectrometry was developed. Lettuce was directly extracted by ultrasound-assisted extraction with methanol, this extract was combined with water, extracted by solid-phase microextraction in immersion mode, and analyzed by gas chromatography with mass spectrometry. Good linear relationships (25-250 ng/g, R > 0.9702) and low detection limits (1.0-25 ng/g) were obtained for analytes along with acceptable precision for almost all analytes (RSDs < 20%). The validated method was applied for the determination of personal care product ingredients in commercial lettuce and lettuces grown in soil and irrigated with the analytes, identifying the target analytes in leaves and roots of the latter. This procedure is a miniaturized and environmentally friendly proposal which can be a useful tool for quality analysis in lettuce.

“…Layered double hydroxides (LDHs) are nanomaterials structured in a 2D form that consist of positively-charged layers of metal hydroxides separated by an interlayer region containing anions and some water molecules between layers [71,72]. Figure 4 shows a schematic overview of LDHs.…”

“…It should also be noted that because of this dissolvable feature, dispersive SPE (dSPE) is the most usual mode of extraction. This practice, using dissolvable LDHs, has been further exploited in various studies [71,73]. Table 2 shows some selected examples of the application of LDHs in SPE.…”

This review provides an overview of the most recent developments involving materials for solid-phase extraction applied to determine organic contaminants. It mainly concerns polymer-based sorbents that include high-capacity, as well as selective sorbents, inorganic-based sorbents that include those prepared using sol-gel technology along with structured porous materials based on inorganic species, and carbon nanomaterials, such as graphene and carbon nanotubes. Different types of magnetic nanoparticles coated with these materials are also reviewed. Such materials, together with their main morphological and chemical features, are described, as are some representative examples of their application as solid-phase extraction materials to extract organic compounds from different types of samples, including environmental water, biological fluids, and food.

“…The most used sample preparation processes are filtration, dilution, extraction, or analyte derivatization. Analytical sample preparation is a field constantly evolving due to the development of novel materials for SPE [6–8], and solvents for LLE [9,10]. Other advances in sample preparation are the development of innovative approaches and devices for the automation of the analytical procedure [5,11–13], opening new possibilities for chemical analysis, or improving existing analytical methods in terms of reproducibility, robustness, and miniaturization.…”

In the last 5 years, additive manufacturing (three-dimensional printing) has emerged as a highly valuable technology to advance the field of analytical sample preparation. Three-dimensional printing enabled the cost-effective and rapid fabrication of devices for sample preparation, especially in flow-based mode, opening new possibilities for the development of automated analytical methods. Recent advances involve membrane-based three-dimensional printed separation devices fabricated by print-pause-print and multi-material three-dimensional printing, or improved three-dimensional printed holders for solid-phase extraction containing sorbent bead packings, extraction disks, fibers, and magnetic particles. Other recent developments rely on the direct three-dimensional printing of extraction sorbents, the functionalization of commercial three-dimensional printable resins, or the coating of three-dimensional printed devices with functional micro/nanomaterials. In addition, improved devices for liquid-liquid extraction such as extraction chambers, or phase separators are opening new possibilities for analytical method development combined with high-performance liquid chromatography. The present review outlines the current state-of-the-art of three-dimensional printing in analytical sample preparation.
