Fast-sequential determination of cadmium and copper in milk powder and infant formula by direct solid sampling high-resolution continuum source graphite furnace atomic absorption spectrometry

Novel nickel trap coupled with electrothermal vaporization for the direct solid-sampling analysis of cadmium in soil

“…Compared with the solid-sampling SS-GFAAS, 41–43 the LOD of this work was comparable but the test required a longer analysis time due to the preconcentration (trap and release) process. However, this ETV-NT apparatus utilized a bigger sample size (≤25 mg); furthermore, this foamed nickel material was characterized with porosity, good heat conduction, ease-to-shape, and anti-oxidization properties.…”

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…Two publications described solid-sampling CS-ETAAS, one for the analysis of milk powder and infant formula, the second for dried blood spots. In the first, Gómez-Nieto et al 80 reported measuring the concentrations of Cd and Cu. The method was comprehensively validated using ERM-BD150 skimmed milk powder, with optimisation of the temperature furnace heating programmes and chemical modifiers.…”

“…Gómez-Nieto et al 80 utilised the difference in atomisation temperature between Cd (900 °C) and Cu (2100 °C) to develop a direct solid sample method for their sequential determination in milk powders and infant formula by HR-CS-GFAAS , achieving LOQs of 2.1 μg kg −1 , for Cd, and 1.7 mg kg −1 , for Cu. Optimisation was carried out using a skimmed milk powder CRM (ERM-BD150), that was also prepared by MAD for comparison.…”

Simultaneous Or Sequential Multi-Element Graphite Furnace Atomic Absorption Spectrometry Techniques: Advances Within The Last 20 Years

“…16 A very important feature of this instrument is that it can perform simultaneous or sequential multi-element analysis (Tables 2 and 3). The HR-CS-GFAAS technique was mainly applied for the simultaneous or sequential multi-element analysis of foodstuffs, 82,87,109,123,125,92,93,99,[102][103][104]106,108 environmental media, 79,82,111,112,117,122,85,86,90,94,96,100,108,110 crude oil [75][76][77] and biological specimens. 80,107 Twenty-eight elements were determined by this technique and Fe, Ni, Cd and Co were the most frequently examined.…”
