Introduction

This regulation is compiled in accordance with JJF1002-2010 "Rules for Compilation of National Metrological Verification Regulations". This regulation is for Revision of JJG 1051-2009 "Electrolyte Analyzer". Compared with JJG 1051-2009, except for editorial changes, The main technical changes are as follows. --- The term "cross-contamination rate" is changed to "carry-over contamination rate" (see Chapter 3); --- Added the relevant content of Li and iCa2 (see Chapter 5); --- Modified the indication error requirements of K, Na, Cl- (see Chapter 5); ---Appendix B adds the preparation method of Li, iCa2 linear solution. The previous versions of this regulation have been released as follows. ---JJG 1051-2009. Electrolyte analyzer verification procedures

1 Scope

This regulation applies to the use of ion-selective electrode method to determine the concentration of K, Na, Cl-, Li, iCa2 in medical Initial verification, subsequent verification and in-use inspection of electrolyte analyzers.

2 Reference documents

GB/T 14710-2009 Environmental requirements and test methods for medical electrical appliances GB/T 6682-2008 Specifications and test methods for water used in analytical laboratories YY/T 0589-2016 Electrolyte Analyzer For dated references, only the dated version applies to this regulation; for undated references The latest version (including all amendments) applies to this regulation.

3 Terminology

3.1 Carry-overrate The discrete amount of analyte carried by the measurement system from one test sample reaction to another test sample reaction, determined by This erroneously affects the performance of another test sample. Usually given a low value sample and a high value of a known nominal setting Value samples are cross-measured multiple times and calculated using a specific formula.

4 Overview

The electrolyte analyzer adopts the ion-selective electrode method. The battery potential formed by the specific electrode is used to measure the ionic activity in the electrolyte solution. Cell potential and specific ionization in solution The relationship of the sub-activity conforms to the Nernst equation. E=E0± RT nFlnαx (1) αx=fx·cx (2) where. E---Measure battery potential, mV; E0---Measure the initial potential value of the battery, mV; R---gas constant, 8.3145J/(K mol); T---thermodynamic temperature of the solution to be tested, K; n---the valence of the tested ion participating in the electrode reaction; F---Faraday constant, 96485C/mol; αx---the activity of the measured ion, mol/L; fx---activity coefficient;
