Product Introduction
Green Union developed and innovated silica (silica gel) microsphere synthesis technology and developed a series of uniform high-purity porous silica microspheres, which can provide silica gel fillers with any size and uniform particle size from 1.7 microns to 50 microns. The pore sizes can be 120 Å, 300 Å and 500 Å. At the same time, green mall combines the unique surface chemical bonding and tail sealing technology to develop reversed-phase silica gel fillers with high column efficiency, high mechanical strength and low back pressure. The fillers include reversed-phase C18, C8 and C4. They are widely used in many fields such as medicine, environment and food to meet the different needs from laboratory analysis to industrial large-scale preparation. Green mall attaches importance to fillers and manufacturing processes and strictly requires the reproducibility between batches. Due to the controllable preparation and surface bonding technology of Silica Gel Microspheres and the strict control of the production process of silica gel microspheres, green mall ensures that silica gel chromatographic fillers have high inter batch reproducibility. The retention time error of silica gel filler between different batches is within 0.3%.
Characteristics of silica gel chromatographic filler:
spherical with uniform particle size and height
optimized aperture structure
high mechanical strength
low back pressure and high column efficiency
perfect end sealing
Resin
C18 can be customized into hydrophilic, hydrophobic, strong hydrophobic, special for biological small molecule proteins and peptides, acid and alkali resistant
C8 C4 NH2 CN
Particle size: 3μm, 5 μm, 10 μm
