应用石墨炉激光激发原子荧光技术来测定Pb、Cu、Mn、Sn、Al、In、Li和Pt,其检测极限可在微微克至亚微微克范围内,这些元素的动态线性范围是3至4个数量级。由脉冲激光所产生的原子荧光其优点在于可调谐度较宽、峰值功效较高,然而当采用电热原子化时,由于低频(例如20Hz)其激光很少能达到最佳化,所以脉冲激光必需同步, Determination of Pb, Cu, Mn, Sn, Al, In, Li and Pt using graphite furnace laser-induced atomic fluorescence spectrometry with detection limits in the range of pico grams to submicron micrograms and dynamic linearity of these elements from 3 to 4 A few orders of magnitude. Atomic fluorescence generated by pulsed lasers has the advantage of wider tunability and higher peak efficiency, however, when electrothermal atomization is used, pulsed lasers are rarely required for their low frequency (for example, 20 Hz) laser to be optimized Synchronize,
