17 FTIR micro transmission spectra of single resin beads of each sample, from polystyrene sulfonyl chloride resin changing to polystyrene sulfonyl amide resin in solid-phase reaction in water at 0 degree C, 20 degrees C, 40 degrees C, 60 degrees C, were recorded. The reaction was monitored by the means of FTIR microspectroscopy and diffuse reflectance spectroscopy upon the products. It was showed that the pressed single bead as a piece of biscuit was able to give higher quality spectrum. In comparison, 8 diffuse reflectance spectra of each sample were also collected. It seems that the diffuse reflectance spectroscopy is a more easy dealing with and effective method to control the whole reaction. However, the microspectroscopy is the first choice to check the difference between resin beads.
记录了每个样品的单个树脂珠在0℃、20℃、40℃、60℃的水中进行固-相反应时从聚苯乙烯磺酰氯树脂转变为聚苯乙烯磺酰胺树脂的17个傅里叶变换红外光谱（FTIR）微透射光谱。通过对产物进行傅里叶变换红外光谱显微镜和漫反射光谱监测反应。结果表明，压制的单个珠子作为一块饼干能够给出更高质量的光谱。相比之下，还收集了每个样品的8个漫反射光谱。似乎漫反射光谱是一种更易于处理且有效的控制整个反应的方法。然而，显微镜光谱是检查树脂珠之间差异的首选方法。
