Background correction by wavelength modulation using a microcomputer in atomic emission spectrometry

Material characterization with terahertz time-domain spectroscopy Köseoğlu, Devrim; Bilikmen, Kadri Sinan; Department of Physics (2010) Terahertz time-domain spectroscopy systems were developed and used for the anaylsis and characterization of various materials. By using ultra-fast Ti:Sapphire and Er-doped fiber lasers, terahertz time-domain spectrometers of different configurations were constructed and tested. To increase the accuracy and sensitivity of the measurements, the systems were optimized for spectroscopic analysis. MBE grown nominally undoped epitaxial GaAs samples were used for the spectroscopic measurements. These samples were ...
Interference studies in germanium determination by electrothermal atomic absorption spectrometry Anwari, Mohammad Ali; Ataman, Osman Yavuz; Department of Chemistry (1994)
Atom trapping vapor generation atomic absorption spectrometry for inorganicarsenic speciation analysis / Njie, Njaw; Ataman, Osman Yavuz; Department of Chemistry (2014) Speciation analysis is important for arsenic. Novel methods to improve the sensitivity for determination of total arsenic and arsenic speciation have been developed. The techniques basically rely on generation of volatile arsenic species by reaction with sodium borohydride followed by trapping on a W-coil atomizer and finally releasing analyte atoms by heating the atomizer; the system is named as W-coil atom trapping electrothermal atomic absorption spectrometry (WC-ETAAS). Sample solution may be introduced...
Elemental analysis of materials including silicon (100) and (111) crystals with single and double pulsed LİBS Yurdanur Taşel, Elif; Bilikmen, Kadri Sinan; Department of Physics (2012) Laser Induced Breakdown Spectroscopy (LIBS) which is used to determine the elemental content of various samples, inspects the emission spectroscopy of samples of interest for searching certain elements or identifying the unknown content. In this study, spectroscopic analyses of various kinds of metals, namely, Cu, Fe, Mo, Ti, W, some compounds such as CuBe, ZnSe, ZnS, GaSe, some semimetals like Si, Ge and even gases were investigated by means of a compact-commercial portable LIBS system and an independently...
Determination of water samples by electrothermal atomic absoption spectrometry Şimşek, Nail Engin; Ataman, Osman Yavuz; Department of Chemistry (2012) Boron (B) is a rare element on Earth crust with a natural abundance of 0.001%. However, boron content of water and soils may be significantly high in the regions with rich boron reserves. In addition, extensive use of agrochemicals in soils as well as various natural processes increases the boron concentration in water. Despite B is an essential element for all living creatures, it may pose risks at high level exposures. World Health Organization (WHO) has recommended a daily intake of 1 to 13 mg B for adul...
