Overview

In HPLC, contamination of the filter element at the injection port of the chromatographic column often leads to an increase in column back pressure and a decrease in column efficiency. Micro diameter columns are particularly prone to clogging due to the small diameter of their injection port filter element. Saizhi Technology has launched a new LC-10Tvp preparation type liquid chromatograph with a pressure resistant filter, including a filter element, plug, and bracket, which is also suitable for other HPLC preparation systems.

Product Details

Principle:

By controlling the particle size to achieve physical filtration effect, the impact of substances with a diameter greater than the filter aperture on the system is eliminated.

The significant advantages are:

1. Can be used with columns from all different manufacturers;

2. The filter can be cleaned and reused;

3. One time purchase for long-term use.

Liquid phase detection application

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
