Q: What’s the difference between technical Grade Silica Gel and High purity Silica Gel?
A: High purity Silica Gel goes through acid treatment and water treatment based on Industrial Grade Silica Gel. So it has less metal impurities and can get better separation effect.
Q: What storage condition is good for silica gel?
A: Because silica gel has adsorption ability, dry and ventilating place is the best.
Q: Do pore diameter and particle size affect silica gel separation effect?
A: Yes. Silica Gel of different pore diameter can separate different substances. Only when the right pore diameter is choosen, it can get the best separation effect. Otherwise the result will be unsatisfying.
Q: Do pore diameter and particle size affect silica gel separation effect?
A: Yes.

Silica Gel of different pore diameter can separate different substances. Only when the right pore diameter is choosen, it can get the best separation effect. Otherwise the result will be unsatisfying.

Silica gel particle size influences separation time. When reagents though silica gel , it will takes more time to small silica gel , so that the silica gel will have more time to touch with your reagents.

Of course it will be influenced by the environment of your lab and the way you use the silica gel .

Q: What about SANPONT supply ability?
A: Column Chromatography Silica Gel: 5tons productions can be finished in one day. Thin Layer Chromatography Silica Gel Plate: 5000boxes can be completed in one day. Note: 6000㎡storage of every kind of products , 65 workers work for you.
Q: Why do we have to confirm clear product details ?
