“…Comparing to conventional LS FAAS, possibilities of background correction and elimination of interferences are increased because the spectral environment of the analytical line can be completely explored. The greatest advantage of HR-CS FAAS in relation to LS FAAS is the need for only one single lamp for all elements instead of one lamp for each element (Welz et al 2003(Welz et al , 2007Becker-Ross et al 2006;Villanueva-Alonso et al 2009). In the recent years, it was demonstrated in literature a great interest in applying HR-CS FAAS to determine various analytes in food samples (Paz-Rodríguez et al 2015;Ozbek and Baysal 2015;Li and Chen 2014;Brandao et al 2010Brandao et al , 2011.…”

Establishing fast, simple, low-cost, and efficient sample preparation procedures to determine elements in foodstuffs is a relevant aspect for nutritional and health purposes. For this reason, the recently proposed closed-vessel conductively heated digestion system (CHDS) was evaluated for the digestion of milk powder, chocolate powder, and soluble coffee samples aiming for Ca, Cu, Fe, K, Mg, Mn, Na, and Zn determinations by high-resolution continuum source flame atomic absorption spectrometry (HR-CS FAAS) and Cd, Mo, and Se determinations by inductively coupled plasma mass spectrometry with tandem configuration (ICP-MS/MS). The accuracy was evaluated by analyzing two milk certified reference materials digested by the CHDS and a microwave oven for comparison. When using the CHDS, recoveries for the analytes varied from 91 to 104 %. For microwave digestions, recoveries within the 94-109 % intervals were obtained. The method was then applied to the samples. For comparative purposes, the analytes were also determined in the samples after microwave digestion, and the results between the two digestion systems showed no differences based on a paired t test at a 95 % confidence level. Similar analytical blanks were obtained because quartz digestion tubes were used in both digestion systems. The CHDS with quartz tubes is an interesting alternative for laboratories dedicated to large-scale routine analysis because volatile elements usually found in very low concentrations in food samples such as Cd and Se can also be determined.

“…Inductively coupled plasma mass spectrometry (ICP-MS) is an important technique for trace element analysis due to its high sensitivity, multielement capability, and high sample throughput (Becker 2007). However, the main drawback to perform trace element analysis by ICP-MS is related to spectral interferences.…”

“…The limitations of this instrumentation and the possibilities for multi-line monitoring are discussed in detail in previous works, 18,19 so they will not be repeated herein. Also, a paper discussing the evolution of CS AAS, with an emphasis on detector requirements, was published by Becker-Ross et al 77 It suffices to say that, at this point, with the commercially available instrumentation it is in principle possible to determine simultaneously several elements (a paper in which Co, Fe, Ni, and Pb were determined in solid samples has been reported 28 ), but this is more the exception than the rule, and most papers determine only one element and, in a few cases, two. It is also important to stress that this limitation is more relevant for GFAAS than for flame AAS, because in the latter case a fast sequential method may be sufficient in most practical situations, and the current instrumentation already enables such approach.…”

A method of flame ato mic absorption analysis has been developed which does not need a light source, such as hollow-cathode lamp, wh ich to produce the radiation absorbed by the analyte atoms. Light emission fro m the analyzed atoms in the flame can serve as a light source because this emission has the same wave length as the resonance absorption line of the unexcited analyte atoms. At certain conditions, in the flame can take place an absorption process known as self-absorption. In the work self-absorption occurring in the flame is used to determine absorbance. Absorbance is calculated fro m the flame emission intensity signal of the analyte atoms. A co mputer program is specially created to calculate absorbance, to draw the calibration curve and to co mpute the analyte concentration. For safety purposes ethyl alcohol is used as a flame fuel and is applied as an alcohol vapor / air flame. Because this flame has low temperature, only lithiu m, potassium, sodium, calciu m, bariu m is able to be analyzed.
