“…Owing to its robustness, simplicity, high sensitivity and cost-effectiveness, FF-AAS plays a unique role in ultra-trace analysis of various elements in a variety of sample matrices. [6][7][8][9] Because of the oxidative atmosphere inside the flame furnace, simultaneous sample digestion and determination inside the tube (flame furnace) can be easily achieved using slurry sampling. [10][11][12] In particular, using FF-AAS as an on-line element-selective detector for capillary electrophoresis has also been a success.…”

“…The addition volumes were 50, 100, 150 and 200 mL; the concentrations added were therefore 2, 4, 6 and 8 ng/mL, respectively. For Mg and Zn, urine analysis FFAAS was applied 50 in the GBC 909 AA atomic absorption spectrometer employing a GBC quartz atom trap cell (Australia) and Photron hollow cathode lamps (Australia). The optimised conditions for Mg and Zn analysis are presented in Table 1.…”

ObjectivesTo evaluate the short-term 24 h urinary excretion of platinum, arsenic, selenium, magnesium and zinc in patients with lung cancer and with cancer other than lungs treated with cisplatin or/and carboplatin from Antofagasta, Chile.DesignUrine measurements of Pt and Se were made by inductively coupled plasma optical emission spectrometry, As by hydride-generation atomic absorption spectrometry and Mg and Zn by means of flame furnace atomic absorption spectrometry.SettingAll samples were provided by the Oncological Centre of Antofagasta Regional Hospital (Region of Antofagasta, Chile).ParticipantsNinety 24-h urine samples from cancer patients after the infusion of Pt-base drugs and 10 24-h urine samples from cancer patients not treated with metal-base drugs.Main outcome measuresConcentrations of Pt, Se, As, Zn and Mg coming from 24-h urine samples.ResultsPt excreted was not significantly different between patients with lung and other cancers treated with cisplatin. The excretion of Mg, Zn and Se was greater than As. Then, Pt favours the excretion of essential elements. For lung and other types of cancers treated with drugs without Pt, excretion of Mg, Zn and Se was also greater than that of As, suggesting antagonism Mg-Zn-Se–anti-cancer drug relationship.ConclusionsThe amounts of Mg, Zn and Se excreted were greater than for As either with or without Pt-containing drugs, suggesting antagonist Mg-Zn-Se–anti-cancer drug relationships. The excretion of As, Mg, Zn and Se is induced by Pt. Knowledge obtained can contribute to understanding the arsenic cancer mechanism and the As-Mg-Zn-Se-Pt inter-element association for lung cancer and other types of cancer.

“…Roman-Silva et al 169 devised liquid-liquid extraction (LLE) procedures for the determination of Ag, Al, Ba, Be, Bi, Cd, Co, Cr, Cu, Fe, Mn, Mo, Pb, Sr, Tl and V by either FAAS with hydraulic high pressure nebulization (HHPN) or a technique referrred to as ''flame furnace'' AAS, also with HHPN. The methods, which included back extraction, were applied for the analysis of river and sea-water, river and marine sediments, soft tissue of mussels, tunicate siphons, aquatic plants, and samples of clinical interest such as placentas, umbilical cords, and cardiovascular tissues from surgical procedures.…”
