What is Seeding?

Seeding is the manfacturing method of producing chromatographic resin beads that are mono-sized and ultra-fine. The beads produced have an extremely narrow particle size distribution and are usually between 5 - 50 μm in size, although in some cases seeding can be used to produce larger beads. 

These resins are perfect for reverse phase chromatography, HPLC or for applications where precise measurement is needed, such as equipment calibrations and measurement. 

Resins produced with Seeding technology can be manufactured to have either non-porous or macroporous properties, depending on customer requirements for their process. 

Advantages of Seeding

As the beads produced are uniform in size this results in improved performance in areas such as:

  • Resolution (efficiency & selectivity)
  • Loading capacity
  • Back pressure/speed (size, porosity)
