Quality control of the silica supports

The rigorous quality control procedure set by YMC starts with the YMC*Gel silica supports. The silica support is tested against demanding specifications which include:
particle size and distribution, pore size and distribution, surface area, pore volume, pH and metal content, etc.

Only when the bulk silica satisfies YMC’s strict specifications for each criterion can the lot be allowed to proceed to bonding.
