Introduction

JJG 823-2014 "Ion chromatography" is written JJF1001-2011 "Universal metering and fixed term Justice ", JJF1002-2010" national verification procedures to write the rules "as the basis and foundation of JJG 823-1993 "Ion Chromatography" subject to revisions. Compared with JJG 823-1993 "Ion chromatography", in addition to editorial changes, the main technical content are as follows Variety. --- Increased UV-Vis detector and an electrochemical detector test specifications. (See 1) --- The original protocol column and instrument of integrated technical indicators, technical indicators to the instrument, and from this canceled Sub-column related technical indicators, such as the separation column and the last peak time. (See section 3.3, 3.4) --- For the original procedure was repeated linear range and correlation coefficient Technical indicators cancel the linear range, correlation coefficient reserved Number of technical indicators. --- Increasing the minimum detectable amount of the instrument to convert the relationship between the sample loop. (See section 5.2.2.4) The previous versions of the release JJG 823 case. --- JJG 823-1993. Ion chromatography test procedures

1 Scope

This procedure is applied with a conductivity detector, UV-Vis detector and an electrochemical detector first ion chromatography Second test, verification and subsequent use of checks.

2 Overview

Ion chromatography (hereinafter referred to as equipment) by infusion systems, injection systems, separation systems, detection systems and several According to the analysis device and other components of the processing system, FIG. 1 is a schematic view of its composition. Because each component ions in the sample Differences in distribution and adsorption properties of the stationary phase and mobile phase, mobile phase has different ions into the elution Detector, according to the order to give the signal intensity of each ion to be measured. According to the retention time of the components and response (Peak area or peak height) for qualitative and quantitative analysis. Figure 1 a schematic view of the composition of ion chromatography

3 metering performance requirements

3.1 Infusion Systems 3.1.1 infusion line and interface are tight, within a predetermined pressure range allows no leakage. 3.1.2 flow setpoint error (SS) and flow stability (SR) shall comply with the requirements of Table 1. Table 1 flow setpoint error SS and SR stability requirements Flow setpoint/(mL/min) 0.2 ~ 0.5 0.5 ~ 1.0 greater than 1.0 Number of measurements/n 3 3 3 Collection time/min 20 ~ 10 10 ~ 5 5
