Sequential and simultaneous determination of chlorine, iron, and silicon in beer samples by high-resolution continuum source graphite furnace molecular and atomic absorption spectrometry

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

“…As previously noted (Section 1), AAS is no longer widely used for analysis of clinical and food/beverage samples but each year a few niche applications are reported in which CS-AAS offers useful advantages compared to alternative techniques. Within this category, the work of Pires et al 69 is of interest. Using a HR-CS-GF-system, Cl, Fe and Si were simultaneously determined by AAS (Fe and Si) and molecular absorption (Cl as the InCl molecule at 267.2181 nm).…”

“…Beer, as the world most widely consumed alcoholic beverage, has also been studied . One such study 69 looked at Cl − , Fe and Si in beers using HR-CS-GF-AAS following an unusual preparation technique, utilising UV light in the presence of peroxide. The levels of Cl − and Fe are both important in the manufacture of beer, affecting taste, clarity and stability.…”

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.…”
