气体扩散-流动注射分光光度法测定人体血浆中的二氧化碳含量

Determination of Carbon Diox CONTENT ide in Blood Plasma Sample with Flow Injection Spectrophotometry

在一台国产分光光度计上,用气体扩散流动注射分光光度法测定了人体血浆中二氧化碳的含量。讨论了给予液的酸度与流速、接受液的酸度与流速对测定的影响。该法用于血浆的测定具有选择性好,操作简便,节省试液等优点。方法的测定精度为0.9%,回收率在94%～106%之间。

A method was tested for the determination of carbon dioxide in blood plasma by flow-injection anal injection sis with membrane separation。The optimal pH for the donor and acceptor stream was chosen. The precision of the method is 0.9% and the recovery is 94～106%。The procedure is simple, rapid, selective and reproducible。
