containPre mixer, filter, main mixer and pipeline jointsWaiting for components. Filters can further filter impurities in the mobile phase and better protect the chromatographic column. A new type of mixer designed to easily achieve high-pressure mixing and mixing of multiple mobile phases with different flow rates, with a small dead volume, meeting the requirements of dual high-pressure gradient elution users in high-performance liquid chromatography. It can uniformly mix mobile phases of different polarities and flow rates, and can meet the requirements of small proportion mixing of different mobile phases. There are three mixing inlets that can be connected to a three-way pump.

High performance liquid chromatography HPLC detection scheme for doxycycline hydrochloride
-Sample processing procedure-
Accurately weigh an appropriate amount of doxycycline hydrochloride reference substance, add an appropriate amount of 0.01mol/L hydrochloric acid solution, dissolve by ultrasound, and dilute with 0.01mol/L hydrochloric acid solution to a solution containing approximately 1mg doxycycline hydrochloride per 1ml. Shake well, filter through a 0.45 µ m organic system filter membrane, accurately measure 20 µ L, inject into a liquid chromatograph, and record the chromatogram.
-Chromatographic conditions-
Chromatographic column: C18, 4.6 mm*250 mm, Particle size 5 µ m
Mobile phase: Acetonitrile: Acetate buffer solution=25:75
Wavelength: 280nm
Flow rate: 1.0mL/min
