A new, portable, compact design is reported here. The tungsten coil is extracted from a 24 V, 250 W commercial projector light bulb. The coil is housed in a small, aluminum cell. The emission signal exits from a small aperture in the cell, while the bulk of the blackbody emission from the tungsten coil is blocked. The resulting spectra exhibit extremely low background signals. The atomization cell, a single lens, and a small CCD-based spectrometer are mounted on a 1 × 6 × 30 cm ceramic base. The resulting system is robust and easily transported. A 400 W solid state power supply is employed to control the current through the coil. The whole system can be powered by a car battery and controlled with a laptop computer. Fifteen elements are determined with the system (Ba, Cs, Li, Rb, Cr, Sr, Eu, Yb, Mn, Fe, Cu, Mg, V, Al and Ga). The precision ranged from 4.3% to 8.4% relative standard deviation for repetitive measurements of the same solution. Detection limits were in the μ/L range. Accuracy was tested using standard reference materials for polluted water, peach leaves and tomato leaves.","abstract_html":"Tungsten Coil Atomic Emission Spectrometry is an ideal technique for field applications because of its simplicity, low cost, low power requirement and independence from cooling systems.
