Educational Multiwavelength Atomic Emission Spectrometer
A simple multiwavelength emission instrument utilizing a commercial grating monochromator, a fiber optic sensor to collect radiation from an acetylene-air flame, and a CCD detector, has been evaluated for pedagogical value in the undergraduate curriculum. Simultaneous determination of Na, Li, K, Rb at ppb level, and Ca, Sr, Ba at ppm level was achieved. The instrument is affordable, yet suitabl...
متن کاملThe Grating Spectrometer and Atomic Spectra
In the previous experiment diffraction and interference were discussed and at the end a diffraction grating was introduced. In this lab most of the things learned in the last experiment will be applied to measure the wavelengths of the lines in the visible spectrum of some elements. You will use a diffraction grating mounted on a spectrometer to measure the interference maxima for various wavel...
متن کاملPreconcentration of Cu(II)with magnetic nanocomposite sorbentsprior to determination by Flame Atomic Absorption Spectrometer
A simple, highly sensitive, accurate and selective method for determination of trace amounts of Cu2+ in water samples .In this paper, Chitosan was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-CHITOSAN sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a novel nano-Fe3O4-Chitosan-ED.Flame atomic abs...

متن کاملTropospheric Emission Spectrometer nadir spectral radiance comparisons
[1] The fundamental measurement of the Tropospheric Emission Spectrometer (TES) on board the Aura spacecraft is upwelling infrared spectral radiances. Accurate TES retrievals of surface and atmospheric parameters such as trace gas amounts critically depend on well-calibrated radiance spectra. On-orbit TES nadir observations were evaluated using carefully selected, nearly coincident spectral rad...
