Significant improvement has been achieved for antimony determination using a slotted quartz tube (SQT) as an atom trap (AT) for in situ preconcentration and flame atomic absorption spectrometry (FAAS). The suggested technique consists of trapping analyte species during ordinary nebulization followed by releasing the collected analyte via introducing organic solvent. Procedures and analytical figures of merit have been presented for the techniques called FAAS. SQT-FAAS and finally SQT-AT-FMS with the relevant comparisons. Analytical parameters, namely composition of the aqueous medium, sample flow rate, flame conditions, distance between burner head and SQT, sampling period and type of organic solvent and its volume have been optimized. Using SQT-AT-FAAS, a sensitivity enhancement of 369 fold has been obtained, 3 s limit of detection was 3.91 mu g L-1 when 25.0 mL of sample was collected in 4.0 min. Interference effects of some elements on antimony signal were studied.

Indium determination using slotted quartz tube-atom trap-flame atomic absorption spectrometry and interference studies Arslan, Yasin; KENDÜZLER, ERDAL; Ataman, Osman Yavuz (2011-09-30) Sensitivity enhancement of indium determination by flame atomic absorption spectrometry (FAAS) was achieved: using a slotted quartz tube (SQT-FAAS) and slotted quartz tube atom trap (SQT-AT-FAAS). SQT was used as an atom trap (AT) where the analyte is accumulated in its inner wall prior to re-atomization. The signal is formed after re-atomization of analyte on the trap surface by introduction of 10 pi of isobutyl methyl ketone (IBMK). Sensitivity was improved 400 times using SQT-AT-FAAS system with respect ...
In situ atom trapping of Bi on W-coated slotted quartz tube flame atomic absorption spectrometry and interference studies KILINÇ, ERSİN; BAKIRDERE, Sezgin; AYDIN, FIRAT; Ataman, Osman Yavuz (2013-11-01) Analytical performances of metal coated slotted quartz tube flame atomic absorption spectrometry (SQT-FAAS) and slotted quartz tube in situ atom trapping flame atomic absorption spectrometry (SQT-AT-FAAS) systems were evaluated for determination of Bi. Non-volatile elements such as Mo, Zr, W and Ta were tried as coating materials. It was observed that W-coated SQT gave the best sensitivity for the determination of Bi for SQT-FAAS and SQT-AT-FMS. The parameters for W-coated SQT-FAAS and W-coated SQT-AT-FAAS ...
SENSITIVITY ENHANCEMENT FOR SLOTTED QUARTZ TUBE FLAME ATOMIC ABSORPTION SPECTROMETRY USING A GAS SCREEN Gholami, Mehrdad; Farjoud, Mohammad Javad; Sepehri, Masoud; Nazari, Ammar; Gholami, Majid; Behkami, Shima; Ataman, Osman Yavuz (2011-01-01) Slotted Quartz Tube (SQT) is a simple device that provides a sensitivity enhancement of 2-5 times in Flame Atomic Absorption Spectrometry (FAAS) depending on the element. A Gas Screen-Slotted Quartz Tube (GS-SQT) was designed to further increase sensitivity. For this purpose, two slotted gas chambers were fixed on the left and right sides of a burner head and Ar gas was supplied into these chambers perpendicular to the light path to produce two thin layers of gas screen. It was observed that these Ar screen...
Sensitive determination of bismuth by flame atomic absorption spectrometry using atom trapping in a slotted quartz tube and revolatilization with organic solvent pulse Kilinc, Ersin; BAKIRDERE, Sezgin; AYDIN, FIRAT; Ataman, Osman Yavuz (2012-07-01) Sensitivity of flame atomic absorption spectrometry (FAAS) for Bi determination was improved by slotted quartz tube (SQT) that was used also for atom trapping (AT). The trapped analyte was released by aspirating a small volume of organic solvent after a reasonable analyte collection time. Sensitivity was improved by 2.9 times by SQT-FAAS and 256 times by SQT-AT-FAAS with respect to FAAS. Optimum trapping period was found to be 6.0 min (36.0 mL of solution). Limit of detection (LOD) for SQT-AT-FAAS was found...
Gas-Screen Slotted Quartz Tube Atomic Absorption Spectrometry: A Remedy for Reducing Interference Effects of Calcium and Chromium Gholami, M.; Yosefi, M. H.; Behkami, S.; Olyai, M. R. Talei Bavil; ARSLAN, YASİN; BAKIRDERE, Sezgin; Ataman, Osman Yavuz (2013-04-13) A simple device for the reduction of nonspectral interferences in flame atomic absorption spectrometry is proposed. It has been reported that the use of a gas screen (GS) system together with a slotted quartz tube (SQT) enhances the residence time of analyte atoms in measurement zone even more than the SQT alone. This combination causes enhancement of sensitivity and improves the reproducibility of absorbance measurements. In addition, it protects the optical windows of the atomic absorption spectrometer.
