摘要
本文描述了流动喷射系统中分散系数与几何参数和流体动力参数之间的关系的实验方程。数据以等色散曲线表示(类似于等温、等压线或等差线表示)。结果给出了一个相关的概述,这使得色散系数的理论计算变得简单。当分散要保持在一定范围内时,可以建立流动注射系统的几何和操作参数。本研究涉及的参数为:管长(100 - 1200mm);管径(0.3-0.8 mm);注射量(93µl);体积流速(0.75-2.0 ml min-1)。
This paper describes experimental equations that relate the dispersion coefficient to the geometry and hydrodynamic parameters of a flow injection system. Data are presented as isodispersion curves (similar to isothermal, isobar or isochore representations). The results present a correlated overview, which makes theoretical evaluation of the dispersion coefficient simple. Geometric and operational parameters for a flow injection system can be established when the dispersion is to be maintained within certain limits. The parameters addressed in this study are: tube length (100–1200 mm); tube diameter (0.3–0.8 mm); injected volume (93 µl); and volumetric flow rate (0.75–2.0 ml min–1).
