Abstract:Silicon absorbance which is dependented on ash and atomization temperature has been studied for uncoated and pyrolytic coated tube and also a variety of metal coating tubes. The sensitivity and linearity for different tubes have been compared. Using the optical temperature control accessory, silica peak height signal was enhanced doubly, reducing atomization time, extending useful time of graphite tube. The effect of time constant, flow rate of inert gas and a series of acids and salts have been investigated. An accurate method for the determination of trace silicon in drinks was established.
Keywords:Optical temperature control graphite furnace atomic absorption spectrometry  Driks analysis  Silicon
