“…Note that a recent report indicated that continuous usage of the ACH containing cosmetic products allows transdermal absorption of cutaneous generated hormones and pheromones and as a link to breast and prostate cancers [6]. Detection of aluminum concentration from the real samples are extensively carried out using various techniques such as inductively coupled plasma atomic emission spectrometric (ICP-AES) [7,8], flame atomic absorption spectrometric (FAAS) [9,10] and atomic absorption spectroscopic techniques [11][12][13]. Unfortunately, all these methods have time consuming operation procedures, including extensive preconcentration of the analyte.…”

A screen-printed silver strip with a built-in three-in-one electrode (SPAgE) configuration of Ag-working, Ag-counter and Ag/Ag(x)O (silver oxides) pseudoreference electrodes has been developed for sensitive and selective electrochemical flow injection analysis (FIA) of aluminum chlorohydrate (ACH) present in antiperspirants, through the free Cl(-) ion liberated from ACH in aqueous medium, as a redox signal at Ag-working electrode in pH 6 phosphate buffer solution (PBS). The solution phase and instrumental parameters were systematically optimized. The calibration graph was linear in the window 1-200 ppm concentration of ACH and the lowest detection limit (S/N = 3) was 295 ppb with a slope of 0.0989 mu A/ppm and regression coefficient of 0.998. Calculated relative standard deviation (RSD) values for the detection of 5 and 50 ppm ACH by this method are 2.21% and 2.16%, respectively. Four different antiperspirant deodorants real samples with and without ACH content were successfully analyzed and the detected values obtained were found to be in good agreement with the product labeled values

A method was developed for the quantitative determination of total vanadium concentration in mussels via electrothermal atomic absorption spectrometry (ETAAS). After the microwave digestion of the samples, a program using temperatures of 1600 degrees C and 2600 degrees C for ashing and atomization respectively, without any matrix modifiers, allowed us to obtain results that were satisfactory since they agreed closely with certified reference material values. The detection limit was 0.03 mg kg(-1) (dry weight), indicating that the method is suitable for the analysis of mussel samples. This determination was compared with matrix modifiers that have been reported previously. The method was applied to various cultivated and wild mussels from the Galician coast, yielding levels below 1 mg kg(-1) (wet weight).

“…Although ion-selective electrodes are readily available for detecting specific metal ions, they can only detect one type of metal ion, and they are difficult to be miniaturized. On the other hand, atomic adsorption spectrometry (Bannon et al, 1994;Parsons and Slavin, 1993;Tahan et al, 1994) and inductively coupled plasma mass spectrometry (Aggarwal et al, 1994;Liu et al, 1999;Bowins and McNutt, 1994) can be used to detect and quantify multiple metal ions simultaneously, but they are not real-time and the instruments are expensive. Considering the limitation of existing technologies in metal ion detection, we exploited oligopeptide-modified SiNW arrays (fabricated by "topdown" approach) for detecting Cu 2+ and Pb 2+ simultaneously at two different channels.…”
