电解质分析仪测定人工肾透析液的含量

Deter Mination of Dialysis Solution for Artificid Kidney by Ion Selective Electrode (ISE) Analyzer

目的:直接测定人工肾透析液中Na+、K+、Cl-的含量;方法:采用Chiron 644 ice电解质分析仪,适当稀释人工肾透析液,一次性测定。结果:样品重现性RSD Na+0.124%,K+0.602%,Cl-1.083%。方法:平均回收率为100.2%Na+,98.79%K+,99.77%Cl-。结论:该测定方法简便、快速、结果准确可靠。

Objective To determine directly the concentrations of Na+、K+、Cl-in dialysis solution.Methods The Chiron644 Na+/K+/Cl-Analyzer was used,diluted the dialysis,for once measure.Results The satisfactory RSD of the sample 0.124%(Na+),0.602%(K+),1.083%(Cl-),and the averaged reconvenes:100.2%(Na+),98.79%(K+),99.77%(Cl-);Conclusion The methed is sensitive,rapid and accurate.
