Introduction

JJG 705-2014 "LC" is prepared JJF1001-2011 "Universal metering and fixed term Justice ", JJF1002-2010" national verification procedures to write the rules "as the basis and foundation of JJG 705-2002 "LC" subject to revisions. Compared with JJG 705-2002 "liquid chromatography", in addition to editorial changes, the main technical content of this Regulation The following changes. --- Increased evaporative light scattering detector; --- Deleted shift error detector test project; --- Fluorescence detector calibration reference material to naphthalene - methanol solution; --- A differential refractive index detector calibration using standard materials to methanol solution of cholesterol; --- Machine qualitative reproducibility from the original 1.5% revised to 1.0%; --- Detector baseline noise and drift to the acquisition time from 1h 30min. The previous versions of the release JJG 705 case. --- JJG 705-2002; --- JJG 705-1990. Liquid chromatography test procedures

1 Scope

This procedure is applied with UV - visible detector, a diode array detector, fluorescence detector, differential fold Optical index detector and evaporative light scattering detector for liquid chromatography initial verification, use and subsequent verification check. 2. References JJG 537-2006 fluorescence spectrophotometer

3 Overview

Liquid chromatography (hereinafter referred to as equipment) by infusion systems, injection systems, separation systems, detection systems and several According to the analysis instrument chain part of the processing system, FIG. 1 is a block diagram of its composition. Liquid chromatograph according to each sample Difference stationary and mobile phase component distribution in the column or adsorption characteristics of the sample into the mobile phase chromatography Separation column, detector and recorded by a data processing system through the chromatograms, retention times of the components based on And response value (peak area or peak height) for qualitative and quantitative analysis.

1 is a block diagram composed of liquid chromatography
