Packing material for preparative

Packing material for preparative

Complete quality control packing materials are carried out and batch-to-batch reproducibility is obtained. Since there are a variety of functional groups and particle sizes, YMC*GELs are used not only in Japan but in overseas.



In order to select column size...

Table1 provides a rough guide to the selection of column inner diameters and packing material particle sizes. It is very important to select the correct column size, considering sample load, column efficiency, pressure and cost of packing material.
Appropriate, Most appropriate on the table indicate particle size of the appropriate inner diameter of each column.

YMC Spherical gel effective for pretreatment and posttreatment of sample

It is recommendable that packing materials whose larger for batch treatment, flush chromatography and open columns as pretreatment of sample(decolorization, concentration, partial purification). They can be used for concentration and desalting of fraction liquid which is after chromatography as well. We have a good reputation for providing high quality spherical packing material for open columns and flush chromatography at a competitive market price.
