Often only small amounts of sample are available for spectroscopic analytical determinations. This work investigates the enhancement of signal in columns packed with silica particles. We propose that silica particles cause the light to scatter through the column, effectively increasing optical path length. Packed columns are shown to be effective with fluorescence spectroscopy, but results were inconclusive with absorbance spectroscopy.

散射介质中的增强荧光

通常只有少量样品可用于光谱分析测定。这项工作研究了填充硅胶颗粒的色谱柱中信号的增强。我们建议二氧化硅颗粒使光通过柱散射，从而有效地增加光程长度。填充柱显示对荧光光谱有效，但结果对吸收光谱没有定论。
