Gel Permeation Chromatography (GPC)

Brand KN

Product origin Dalian,China

Delivery time deliver as soon as received payment

Supply capacity 30 sets one month

GPC gel purification system has many advantages such as high purification rate, simple operation, convenient maintenance, safety and reliability. It is mainly used in the pre-treatment and purification process of samples for the detection of pesticide and veterinary drug residues, polycyclic aromatic hydrocarbons, and polychlorinated biphenyls. It is widely used in the fields of agricultural products, food, environment and life sciences.

Gel Permeation Chromatography (GPC)

KN-300 Gel Permeation Chromatography (GPC)

 

Overview

As we have seen, GPC/SEC is a type of LC and so solid stationary and liquid mobile phases are again used. However, the separation mechanism here relies solely on the size of the polymer molecules in solution, rather than any chemical interactions between particles and the stationary phase.


Features

1. High-precision high-pressure constant-flow pump, stable infusion, good repeatability

2. Real-time pressure display, high and low pressure alarms and other functions to ensure the safety of the instrument

3. Variable wavelength ultraviolet-visible detector, wide wavelength range, high sensitivity

4. Touch screen automatic fraction collector, easy to operate and intuitive

5. Stainless steel and quartz glass gel purification columns are optional, with good consistency, shortening operation time and improving work efficiency

6. Floating self-calibration sealing ring technology and patented technology of pump head self-cleaning function, which can extend the service life of the sealing ring and ensure the durability and high efficiency of the instrument

7. Convenient and easy-to-use flow and pressure correction function to ensure the high precision and stability of the instrument

8. Adopt two kinds of gradient running program design: linear gradient and step gradient are optional

9.Programmable solvent type and compression factor, which can automatically compensate for the complete pre-cleaning function, which is convenient for quick solvent replacement

10. Adopts high-precision photodiode design, linear range expansion

11. Convenient and unique light intensity gain coefficient self-correction function

12. Unique holmium glass cell design, full wavelength scanning, convenient and accurate wavelength correction

13. Universal sample cell design, easy to change between micro and constant cell
