Phellodendri Amurensis Cortex (PAC) is a well-known herbal medicine in China with complex components, but the previous research has mostly focused on its alkaloids analysis. For the first time, a simpler and more efficient method was proposed in this paper to simultaneously determine the content of three different kinds of compounds—phenolic acids, alkaloids and limonoids—in PAC
These pumps are ideally used where fast and highly precise dosage is required. Five series guarantee a flow rate from 1 µl/h to 1152 ml/min and a pressure up to 150 bar. Micro annular gear pumps are characterized by low pulse delivery, minimal dead volume, long service life, small dimensions, powerful materials and ease of maintenance.
