IIIPost column derivatization device for liquid chromatographyInstrument features:

1. In order to ensure the key performance indicators of the instrument, all core components of the reagent pump are imported, and the proportion of imported components in the entire instrument reaches over 80%; The main indicators for determining SHU liquid pumps are high pressure indicators, and all sealing system components of Huamei Chen Company are imported from the United States. The motor drive that determines the stability and accuracy of flow is imported from Japan. The pulsation damper that suppresses pulsation is designed by Huameichen Company.

2. The derivative system adopts imported derivative pipelines and flow limiters to ensure the stability of the baseline and the separation degree of each measured substance.
