流动注射分析中混合釜体积与进样量的关系

Relationship between the Volume of Mixing Tanks and Injected Sample Volume in Flow Injection Analysis

在流路系统和载流流速一定且进样体积不大于反应器体积的０．４５倍时，系统混合釜总体积Ｖｍ与进样体积Ｓｖ的关系可表示为：Ｖｍ＝（ａ＋ｂＳｖ）／（１＋Ｓｖ），ａ和ｂ为与实验条件有关的常数。单釜体积为定值，与进样体积无关，在流路系统和进样体积一定时，混合釜总体积为定值，与载流流速无关。

For a given manifold and flow rate and the sample volume is not greater than 45/100 reactor volume, the relationship between total volume of mixing tanks V. and inject- ed sample volume Sv. can be expressed as: Vm= (a+bSv)/(1+Sv),where a and b are coeffi- cients which depend on experimental conditions, and the volume of single tank is a constant which is independent of the sample volume. For a given manifold and samp1e volume, the to- tal volume of mixing tanks is a constant which is independent of the carrier flow rate.
