  • LASER EXCITED ANALYTICAL ATOMIC AND IONIC FLUORESCENCE IN FLAMES, FURNACES AND INDUCTIVELY COUPLED PLASMAS - II. FLUORESCENCE CHARACTERISTICS AND DETECTION LIMITS FOR FOURTEEN ELEMENTS

Abstract

An account is given of the analytical characteristics of the elements Al, B, Ba, Ga, Mo, Pb, Si, Sn, Ti, Tl, V, Y, Zr and U in atomic and ionic fluorescence spectrometry using an excimer (XeC1) pumped pulsed dye laser as excitation source. The inductively coupled argon plasma was mainly used as atom - ion reservoir. The detection limits were found to be in the range 0.4-20 ng ml**-1, improving "standard' tabulated ICP emission values by factors between 1 and 66. The seperated air - acetylene flame and the carbon rod were also used as atom reservoir for a few volatile elements, the practical detention limit for lead with the latter being 6 x 10 -15-g. The advantages and disadvantages of such an analytical system are discussed, one of the main advantages being certainly the high spectral selectivity of the technique.
