Our research group mainly deals with analytical method development in atomic and molecular spectrometry. Current research topics may be summarized as follows:

 

Atom trapping atomic spectrometry: Our group has developed novel traps using quartz or tungsten traps. Atom trapping is based on initial formation of a vapour containing analyte followed by trapping these species on a surface and a final step in which the preconcentrated analyte species are removed from the trap and sent to atomizer. So far, quartz tubing heated to a certain level has been used as a trap for Sb, Pb and Cd. Tungsten wire has also been used as an on-line trap for Bi, Pb and Cd. For both systems detection limits at the order of ng/L has been obtained using a quartz tube and AAS detection. Cold quartz atomizer has been used for Cd. These systems are capable of working with other atomizers such as ICP-OES and ICP-MS. We shall be working on these systems in future. In addition to developments of traps we are also working on the nature of interferences in these systems. Another branch of studies in this group is electrochemical vapour generation coupled to atom trapping.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Determination of trace elements for practical applications. Our group is also interested in determination of essential and toxic elements in herbs and spices as well as biological samples such as blood, urine, hair, etc. .

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

One of the ongoing projects is the estimation of human daily boron exposure in boron-rich areas in Turkey. As it is assumed that the B levels in urine and blood reflect daily B exposure,the amount of B in urine and blood of both the study and control groups is analysed using ICP-OES and ICP—MS.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Archaeometry studies. Trace element analysis can be utilized for archaeometric studies. Provenance analysis using trace element concentrations in obsidian artifacts from Çatalhöyük excavation (Central Anatolia, Turkey) was on of the studies undertaken during an MSc. Thesis. A recent project is the provenance analysis in limestone figurines obtained in Emecik, Datça excavations (Aegean region, Turkey) using trace element concentrations including REE; ICP-MS and ICP-OES were used in this study.
