“…Direct interfacing to MS are less widespread compared to chromatographic approaches, although different direct couplings have been realized over the last years [5]. A variety of geometrical configurations of SPME were used for diverse applications, including environmental [6], bioanalytical [7] and food analysis [8]. One example of direct coupling is based on the direct introduction of the fiber inside the high vacuum region of the ionization source (e.g., electron impact, EI) before mass spectrometric detection.…”

We report a new strategy for the direct coupling of Solid-Phase Microextraction (SPME) with mass spectrometry, based on thermal desorption of analytes extracted on the fibers, followed by ionization by a dielectric barrier discharge ionization (DBDI) source. Limits of detection as low as 0.3 pg/mL and a linear dynamic range of ≥3 orders of magnitude were achieved, with a very simple and reproducible approach. Different from direct analysis in real time (DART), desorption electrospray ionization (DESI), or low-temperature plasma (LTP), the desorption of the analytes from the SPME devices in our setup is completely separated from the ionization event. This enhances the reproducibility of the method and minimizes ion suppression phenomena. The analytes were quantitatively transferred from the SPME to the DBDI source, and the use of an active capillary ionization embodiment of the DBDI source greatly enhanced the ion transmission to the MS. This, together with the extraordinary sensitivity of DBDI, allowed subpg/mL sensitivities to be reached and to skip conventional and time-consuming chromatographic separation.

“…The results were as expected, with higher affinity of the more polar compounds for PA and the nonpolar ones for PDMS. [12][13][14][15][16][17][18] The fiber selection was based on the overall best performance (i.e., larger chromatographic peak areas). The selection of the PA fiber was consistent with the findings of Santos et al, 17 who conducted a study comparing PDMS and PA for the extraction of chlorobenzenes in soil using HS-SPME.…”

Solid residues generated by the petroleum industry are often classified as hazardous, in part due to the lack of adequate analytical methods for their characterization, given their gluey and highly viscous nature. In this study, an alternative to the method described by the United States Environmental Protection Agency (US EPA) method 1311, replacing the zero headspace extraction (ZHE) approach with solid-phase microextraction followed by analysis via gas chromatographymass spectrometry was developed, for the determination of aromatic chlorinated and nonchlorinated volatile organic compounds. The method was validated according to national and international regulations, with a working range of 2.00 to 90.00 μg L -1 and limit of detection varying from 0.12 to 0.41 μg L -1 . Spiked matrices were analyzed and recovery values ranged from 79.7 to 98.4%. The analysis of real samples revealed levels below limit of quantification for chlorobenzene derivatives (2.00 μg L -1 ) and for the non-chlorinated aromatic compounds < 19.85 μg L -1, proving to be a viable alternative to overcome the difficulties encountered with filtration techniques.

“…5,6 However, the procedures of sample preparation still represent an obstacle to development of an efficient analytical method. 7 The constituents or coextractives which are present in the sample, be food or environmental, [8][9][10] may be responsible for promote the imprecision and/or inaccuracy in quantification of the species of interest, such as pesticides. This type of interference is known as matrix effect.…”

This paper investigates a strategy as a quality control parameter, using standard surrogate and determination of a relation factor for determination of parathion-methyl, chlorpyriphos and cypermethrin pesticides in environmental aqueous matrices with distinct characteristics (river water, estuarine, seawater and weir water), using the technique of solid phase microextraction gas chromatography with flame ionization detector (SPME-GC-FID). Pesticides were very susceptible to matrix effects promoted by environmental samples. The salinity and the organic matter seem to have been the main sources of interference in the method. For chlorpyriphos, in middle and high levels, the values of relation factor (R f ) for estuarines, seawater and weir matrices were statistically similar. For cypermethrin, the statistical equality occurred in estuarine matrices in medium and high levels of concentration. That indicates proportional behavior between the pesticide and the surrogate recovery, suggesting that a single value of R f can be used as correction factor recovery for any of these matrices.
