Development of high-speed medical electrolyte Analyzer module

摘要

To satisfy the need of electrolyte tests of Automatic Biochemical Analyzer, a flow injection dynamic ion analysis method was proposed based on method and experiments, this new method combined the advantages of Flow Injection Analysis (FIA) and Ion Selective Electrode (ISE). With embedded technology, we developed a new electrolyte module and the clinical trials show that the electrolyte module meets the requirements of clinical application with the Coefficient of Variability (CV) of K⁺, Na⁺ and Cl⁻ are 1.02%, 0.89% and 0.75% is better than the pre-existing analyzers. Compared with Electrolyte Analyzers, its test speed reaches an advanced level (150Samples/h) and can be associated with Automatic Biochemical Analyzer flexibly. The module has certain application prospect in the field of high-speed electrolyte analysis.
