Simultaneous determination of cadmium and zinc using a fiber optic device and fluorescence spectrometry
Ertas, N; Akkaya, EU; Ataman, Osman Yavuz (2000-04-03)
A reservoir type of optode is described for simultaneous and remote determination of Cd and Zn using [9-(1',4',7', 10',13'-pentaazacyclopentadecyl)methylanthracene] as the fluorophore. Simultaneous analysis was achieved by the significant perturbation in the fluorescence spectrum of the Cd-ligand complex while the Zn complex only results in enhancement in the fluorescence intensity as compared to ligand alone. The ion permeability of several membranes were examined; Nafion and cellophane were used for the c...

This paper presents a novel "in operation acceleration sensing and compensation method" for a single-mass mode-matched MEMS gyroscope. In this method, the amplitudes of the sustained residual quadrature signals on the differential sense-mode electrodes are compared to measure the linear acceleration acting on the sense-axis of the gyroscope. By measuring the acceleration acting along the sense-axis, the g-sensitivity of the gyroscope output to these accelerations is mitigated without using a dedicated accel...
Simultaneous determination of bismuth and tellurium using tungsten coil atom trap with inductively coupled plasma mass spectrometry /
Bora, Selin; Ataman, Osman Yavuz; Department of Chemistry (2016)
Atom traps such as slotted quartz tube, quartz plate and tungsten coil have been used in atomic spectrometry in order to preconcentrate analyte hydrides and then detection was done by atomic absorption or fluorescence spectrometry. In this study, tungsten coil atom trap was used for the first time with plasma spectrometry. A novel method, which is called Hydride Generation Tungsten Trap Inductively Coupled Plasma Mass Spectrometry (HG-W-Trap-ICPMS), was developed in the first part of this study. Then as a s...
Simultaneous determination of selected endocrine disrupter compounds in wastewater samples in ultra trace levels using HPLC-ES-MS/MS
Komesli, Okan Tarik; Bakirdere, Sezgin; Bayoren, Ceren; Gökçay, Celal Ferdi (2012-08-01)
An analytical procedure for the simultaneous determination of six selected endocrine disrupter compounds (EDCs: diltiazem, progesterone, benzyl butyl phthalate (BBP), estrone, carbamazepine (Cbz), acetaminophen) was developed by liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-ES-MS/MS). All of the parameters for HPLC and ES-MS/MS systems including mobile phase composition, flow rate, and sample injection volume were optimized to obtain not only the best separation of species int...
Simultaneous thermogravimetry-calorimetry study on the combustion of coal samples: Effect of heating rate
Kök, Mustafa Verşan (2012-01-01)
Combustion characteristics of two different coal samples were investigated using power compensating type differential scanning calorimeter (DSC) and thermogravimetry (TG-DTG) at different heating rates (5, 10 and 15 degrees C/min). Differential scanning calorimeter (DSC) and thermogravimetry (TG-DTG) curves revealed two main reaction regions at each heating rate studied. Reaction regions, peak and burn-out temperatures, weight loss and heat of reactions of the samples were determined. Kinetic parameters of ...
