“…LA-ICP-MS in combination with a calibration methodology based on the deposition of aqueous standards on the film surface, its drying and its final ablation has demonstrated to be an excellent tool for quantitative localized analysis of inclusions in industrial polymeric films. The so-called external dry droplet calibration approach (E-DDCA) is a modified version of the DDCA successfully used for the quantitative bulk analysis of polymers such as polyethylene, polypropylene [ 21 ], as well as alumina and CoMo catalysts, commonly used in petroleum refining processes [ 23 ]. The E-DDCA shows interesting features, because it overcomes the unwanted matrix effects as the matrix for the standards is the sample itself.…”

The present work shows, for the first time, the application of laser ablation connected to inductively coupled plasma mass spectrometry (LA-ICP-MS) to the localized quantitative analysis of inclusions in polymeric industrial films. The multielemental mapping capabilities of LA-ICP-MS has allowed to chemically examine unique defects appeared during the plastic processing. This analytical tool is perfectly suited to detect elements such as Al, Mg, Zr, Ti, Cr, P, Pb, Sb, Zn, and Si in those inclusions. A method for multielemental quantitative analysis of these defects has been developed in the present work. The profiling for more than 100 different defects in three samples has demonstrated that more than 50% of these inclusions contain aggregates of some of the aforementioned elements. Therefore, the distribution of elements used as additives or present in catalysts must be carefully controlled during the production of polymeric films in order to avoid degradation in their performance.

“…[12][13][14][15][16] At the same time there are a number of works describing LA-ICP-MS analysis of liquids evaporated on solid substrates. [17][18][19][20] Previously, the so-called "thin layer technique" was proposed for the analysis of concentrates of traces using a spark source mass-spectrometry (SMS). [21][22][23] This technique allows avoid the dilution of the concentrates and helps reduce significantly the analytes LODs.…”

A combination of trace elements preconcentration and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is proposed for the analysis of high purity substances. The analytical figures of merit of this combination were evaluated using high purity germanium dioxide as an example. Trace elements were preconcentrated by germanium volatization in the form of germanium tetrachloride from sample solutions. The trace elements concentrate was evaporated to dryness on the surface of a high-purity silicon substrate and analyzed by LA-ICP-MS. Indium was used as an internal standard to obtain quantitative data. Limits of detection (LODs) for 47 trace elements are in the range from 0.3 to 300 ppt wt (0.3 to 300 pg g -1 ). The obtained LODs are 10-100 times lower compared to ICP-MS analysis of germanium with preconcentration of trace elements. The accuracy of results was confirmed by comparing with results obtained by the traditional ICP-MS analysis of the trace elements concentrates and by the "spike" experiments.

Citrate-capped gold nanoparticle (GNP) was used as a ligand for chromium chelating, and chromium ions reaction led to GNP aggregation. The color change of GNP by aggregation in the presence of chromium is a simple and rapid colorimetric test for these ions in an aqueous solution. GNP capped citrate was prepared by the citrate method and characterized by TEM, and its particle size was 20 nm. Also, the surface plasmon resonance (SPR) peak was 520 nm. In the presence of chromium ions, the color of GNP at 520 nm was shifted to 650 nm because of aggregation to give a signal as a ratio of A650/520 more than one and proportional with chromium concentration directly. The optimum conditions were studied to obtain the high signal represented by the volume of GNP, reaction kinetic of A650 with time, selectivity, and interferences of Zn(II), Fe(III), Fe(II), Sn(II), Ni(II), Ca(II), Al(III), Sr(II), Cu(II), Mn(II), Co(II), Mg(II), Ag(I), and Pb(II) ions. The calibration curve is linear in the range of 100–500 ppb, and the regression was 0.9951 and applied on tap water chromium ions in the same range in the regression of 0.95. This method was simple, rapid reaction, consumed low volumes of sample, and had low detection limits. It can be recommended as a new method for chromium (III) detection in aqueous solutions.
