Some experiments were designed and performed in order to elucidate the mechanism of re-volatilization in silica traps using flame AAS. A water-cooled U-shaped silica trap and a slotted silica tube trap were used, while organic solvent aspiration was employed for re-volatilization. Analytes were Bi, Au, Mn, Cd and Pb. The detailed experiments have shown that heating is not necessarily associated with re-volatilization: however, a direct contact between flame and active silica surface is required. The effect of the critical C/O value in the flame was also investigated and found to be important.

Investigation of polymerization of benzoxazines and thermal degradation characteristics of polybenzoxazines via direct pyrolysis mass spectrometry Fam, Shahla Bagheri; Uyar, Tamer; Ishida, Hatsuo; Hacaloğlu, Jale (2012-10-01) Polymerization of benzoxazines and thermal degradation mechanisms of polybenzoxazines were investigated using the direct pyrolysis mass spectrometry (DP-MS) technique. The benzoxazine structures were based on phenol and aniline and on bisphenol-A and methylamine or aniline. Polymerizations of the benzoxazines were carried out by curing them at elevated temperatures without addition of initiator or catalyst. DP-MS data showed the presence of chains generated by opposing polymerization reaction pathways indic...
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 ...
Investigation of the effect of substituent on the growth of polymer for 3-substituted polythiophenes via pyrolysis mass spectrometry Aslan, Evren; Toppare, Levent Kamil; Hacaloğlu, Jale (2005-10-15) In this study, direct pyrolysis mass spectrometry analyses of electrochemically polymerized poly(decanedioic acid bis-(2-thiophen-3-yl-ethyl)ester) and poly(terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester) were per-formed to investigate structural and thermal characteristics. It was found that when the ester linkages contain hydrocarbon chains, the growth of polymer occurred through both 2- and 5-positions. On the other hand, when the ester linkages contain more rigid groups such as phenyl, steric hindran...
Studies on device properties of an n-AgIn5Se8/p-Si heterojunction diode KALELİ, Murat; Parlak, Mehmet; Ercelebi, C. (2011-10-12) In this study, polycrystalline thin films of ternary AgIn5Se8 compounds with n-type conductivity were deposited on p-type Si substrates from the powder of a Ag3In5Se9 single crystal by a thermal evaporation technique. Transport and photo-transport properties of the In/n-AgIn5Se8/p-Si/Al sandwich structure were investigated by analyzing temperature-dependent dc current-voltage (I-V), and photo-response measurements carried out in the temperature range of 200-360 K. In order to obtain the series resistance (R...
Sensitivity improvement for antimony determination by using in-situ atom trapping in a slotted quartz tube and flame atomic absorption spectrometry TİTRETİR DURAN, SERAP; Sik, Ahmet Inanc; ARSLAN, YASİN; Ataman, Osman Yavuz (2012-11-01) 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 relevan...
