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 procedures1 ScopeThis 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.
