| 摘 要： | 本文指出全内反射长毛细管吸收池(TR-LCC)的最主要特点是有效光路的倍增和测量动态范围的加大,明确定义了有效光路增大比。用简单的分析说明文献3]中吸光度和浓度、吸收管长度成线性关系的原因,并用计算结果予以让实。说明在感兴趣的范围内,非线性关系是成立的。最后给出一个估算TR-LCC中吸光度的理论上更自洽的公式。

| Abstract: | The most important advantage of total reflection long capillary cell (TR-LCC) or optical wave guide cell (OWGC) is multi-fold increasing of effective path length and enlargement of measuring dynamic range. Enhancement ratio of effective path length has been defined. Linear dependence of absorbance on the concentraction of solute and the length of absorbtion tube which was presented in ref. 3], is explained by two simple reasons, and is confirmed with calculated results. Finally a more self-consistent formula for absorbance in TR-LCC is proposed. |
