“…Thus, sol-gel technology has been an interesting tool for the development of new sorbent materials for SPME as it enables different shapes, formats, compositions, and sizes. Moreover, the synthesis can be performed in extraordinarily mild conditions and the materials present several advantages, such as high permeability, large pore structures, and inexpensive preparation (Dugheri et al, 2021;Maciel et al, 2019;Mei et al, 2019;Paiva et al, 2021;Pawliszyn, 2012aPawliszyn, , 2012bSouza et al, 2021;Yavir et al, 2020).…”

“…Furthermore, the extraction of the compounds with low volatility can be facilitated by the heating of the solution, due to modification of the density gradients associated with temperature gradients, and consequently, the constant of Henry's law. Therefore, the extraction time can be decreased with the employ of efficient agitation and/or increase of temperature (Mogaddam et al, 2019;Lambropoulou et al, 2007;Paiva et al, 2021;Pawliszyn, 2012a).…”

“…The number of analytes extracted by direct SPME and headspace-SPME can have variation in the equilibrium concentration, because of several factors, such as volatility and vapor pressure. However, these MEs can show a significant difference in the recovery for many volatile analytes (Lambropoulou et al, 2007;Maciel et al, 2019;Ouyang & Jiang, 2016;Paiva et al, 2021;Wilkes et al, 2000).…”

Carbamates and dithiocarbamates are two classes of pesticides widely employed in the agriculture practice to control and avoid pests and weeds, hence, the monitoring of the residue of those pesticides in different foodstuff samples is important. Thus, this review presents the classification, chemical structure, use, and toxicology of them. Moreover, it was shown the evolution of liquid-and solidphase microextractions employed in the extraction of carbamates and dithiocarbamates in water and foodstuff samples. The classification, operation mode, and application of the microextractions of liquid-phase and solid-phase used in their extraction were discussed and related to the analytical parameters and guidelines of green analytical chemistry.

“…Despite the similar characteristics, NTDs devices have an exhaustive character, being able to deal with larger volumes. The initial NTDs were based in gas samples, although now it is used in a wide range of matrices like water, breath, or urine [ 14 , 17 ]. Thermal desorption tubes are sampling methods based on diffusion; the thermal tubes sorbents have high hydrophobic properties reducing the interference of water—especially suitable for humid samples—but capturing a wide range of volatile compounds [ 18 ].…”

The untargeted urine volatilome for biomedical applications: methodology and volatilome database

2022

View full text Add to dashboard Cite

Chemically diverse in compounds, urine can give us an insight into metabolic breakdown products from foods, drinks, drugs, environmental contaminants, endogenous waste metabolites, and bacterial by-products. Hundreds of them are volatile compounds; however, their composition has never been provided in detail, nor has the methodology used for urine volatilome untargeted analysis. Here, we summarize key elements for the untargeted analysis of urine volatilome from a comprehensive compilation of literature, including the latest reports published. Current achievements and limitations on each process step are discussed and compared. 34 studies were found retrieving all information from the urine treatment to the final results obtained. In this report, we provide the first specific urine volatilome database, consisting of 841 compounds from 80 different chemical classes.

“…The new field of vacuum-assisted sampling techniques, such as vacuum-assisted sorbent extraction (VASE), and the modification of the above-mentioned techniques under reduced pressure, has gained more attention in recent years [ 23 , 24 ]. The characteristics and comparison of the various extraction methods have been repeatedly reviewed [ 25 , 26 , 27 ]; thus, these will not be described in this review in detail.…”

Hyphenated Mass Spectrometry versus Real-Time Mass Spectrometry Techniques for the Detection of Volatile Compounds from the Human Body

et al. 2021

View full text Add to dashboard Cite

Mass spectrometry (MS) is an analytical technique that can be used for various applications in a number of scientific areas including environmental, security, forensic science, space exploration, agri-food, and numerous others. MS is also continuing to offer new insights into the proteomic and metabolomic fields. MS techniques are frequently used for the analysis of volatile compounds (VCs). The detection of VCs from human samples has the potential to aid in the diagnosis of diseases, in monitoring drug metabolites, and in providing insight into metabolic processes. The broad usage of MS has resulted in numerous variations of the technique being developed over the years, which can be divided into hyphenated and real-time MS techniques. Hyphenated chromatographic techniques coupled with MS offer unparalleled qualitative analysis and high accuracy and sensitivity, even when analysing complex matrices (breath, urine, stool, etc.). However, these benefits are traded for a significantly longer analysis time and a greater need for sample preparation and method development. On the other hand, real-time MS techniques offer highly sensitive quantitative data. Additionally, real-time techniques can provide results in a matter of minutes or even seconds, without altering the sample in any way. However, real-time MS can only offer tentative qualitative data and suffers from molecular weight overlap in complex matrices. This review compares hyphenated and real-time MS methods and provides examples of applications for each technique for the detection of VCs from humans.
