流动注射分析中样品分散与反应管长或载流流速关系

Relationship between Sample Dispersion and Reaction Tube Length or Carrier Flow Rate in Flow Injection Analysis

根据串联釜模型，流动注射分析中样品分散系数Ｄ与反应管长Ｌ的关系可表示为：Ｄ＝ ａ ＋ ｂＬ＋ ｃｌｎＬ；在用分光光度法检测时，分散系数与载流流速Ｑ的关系可表示为：Ｄ＝ Ｑ／（ａ′＋ ｂ′Ｑ＋ ｃ′ｌｎ Ｑ） ，式中，ａ，ｂ ，ｃ，ａ′，ｂ′和ｃ′为与实验条件有关的系数．

s On the basis of the tanks in series model, the relationship between sample dispersion D and reaction tube length L in flow injection analysis can be expressed as: D=a+bL+c\%ln\%L; With spectrophotometric detection, the relationship between sample dispersion D and carrier flow rate Q can be expressed as: D=Qa′+b′Q+c′\%ln\%Q, where a, b, c, a′, b′ and c′ are coefficients which depend on experimental conditions.
