“…This promotes a great demand for miniaturized and even portable instruments for field analysis of trace heavy metals. Although traditional analytical atomic spectrometry, including atomic absorption spectrometry (AAS), , atomic fluorescence spectrometry (AFS), , optical emission spectrometry (OES), − and atomic mass spectrometry (MS), − are the most mature and predominant analytical methodologies for inorganic elements, with high sensitivity, selectivity, and accuracy, they also suffer several severe shortcomings for field analysis, including large instruments, high power consumption, and complicated instrumental operation derived from their initial design based on laboratory applications. Therefore, it is greatly desired to develop miniaturized atomic spectrometers for field analysis of heavy metals …”

A new compact tandem excitation source was designed and constructed by using an array point discharge (ArrPD) microplasma for a miniaturized optical emission spectrometer through coupling a hydride generation (HG) unit as a sample introduction device. Three pairs of point discharges were arranged in sequence in a narrow discharge chamber to construct the ArrPD microplasma, for improved excitation capability owing to the serial excitation. Besides, the discharge plasma region was greatly enlarged, therefore, more gaseous analytes could be intercepted to enter into the microplasma for sufficient excitation, for improved excitation efficiency and OES signal. To better understand the effectiveness of the proposed ArrPD source, a new instrument for simultaneous detection of atomic emission and absorption spectral responses was also proposed, designed, and constructed to reveal the excitation and enhancement process in the discharge chamber. Under the optimized conditions, the limits of detection (LODs) of As, Ge, Hg, Pb, Sb, Se, and Sn were 0.7, 0.4, 0.05, 0.7, 0.3, 2, and 0.08 μg L −1 , respectively, and the relative standard deviations (RSDs) were all less than 4%. Compared with a commonly used single point discharge microplasma source, the analytical sensitivities of these seven elements were improved by 3−6-fold. Certified Reference Materials (CRMs) were successfully analyzed with this miniaturized spectrometer, which features low power, compactness, portability, and high detectability, and is thereby a great prospect in the field of elemental analytical chemistry.

“…The preparation involved switchable solvent liquid extraction and, with the slotted tube, the LOQ for the FAAS measurement was 8.6 μg L −1 , a sensitivity increase of 92-fold. Two further reports involved the analysis of green tea 65 and chamomile tea and coffee. 66 Both groups employed DSPE procedures for the initial sample preparation.…”

“…66 Both groups employed DSPE procedures for the initial sample preparation. For the analysis of green tea, Karlidag et al 65 used ZrNPs, prior to measurement of Se by slotted quartz tube FAAS while Saylan et al 66 prepared a Schiff base ligand from the reaction of 5-bromosalicylaldehyde and o -phenylenediamine to form a coordinate nickel complex. The reported enhancement for the Se analysis was approximately 420-fold and 66-fold for the Ni procedure.…”

It is indisputable that separation techniques have found their rightful place in current analytical chemistry, considering the growing complexity of analyzed samples and (ultra)trace concentration levels of many studied analytes. Among separation techniques, extraction is one of the most popular ones due to its efficiency, simplicity, low cost and short processing times. Nonetheless, research interests are directed toward the enhancement of performance of these procedures in terms of selectivity. Dispersive solid phase extraction (DSPE) represents a novel alternative to conventional solid phase extraction (SPE) which not only delivers environment-friendly extraction with less solvent consumption, but also significantly improves analytical figures of merit. A miniaturized modification of DSPE, known as dispersive micro-solid phase extraction (DMSPE), is one of the most recent trends and can be applied for the extraction of wide variety of analytes from various liquid matrices. While DSPE procedures generally use sorbents of different origin and sizes, in DMSPE predominantly nanostructured materials are required. The aim of this paper is to provide an overview of recently published original papers on DMSPE procedures in which metallic nanoparticles and hybrid materials containing metallic particles along with other (often carbon-based) constituent(s) at the nanometer level have been utilized for separation and pre-concentration of (ultra)trace elements in liquid samples. The studies included in this review emphasize the great analytical potential of procedures producing reliable results in the analysis of complex liquid matrices, where the detection of target analyte is often complicated by the presence of interfering substances.
