YMC products must pass our internal performance criteria as raw materials, as synthesised silica particles, as bonded materials, and finally when they are packed into a column. By testing the raw materials and synthesising the silica gel, we can achieve low metal levels of purity. Our acceptance standards virtually eliminate problems with non-specific adsorption caused by trace contaminants in the silica gel.

The premium quality silica is then bonded to provide the selectivity for which the product is designed. YMC’s expertise in HPLC surface chemistry has produced several different proprietary stationary phases. Random samples from the bonded lot are tested for elemental content and then packed into columns and evaluated chromatographically with test samples.

At this point, another accept/reject decision is made before the lot is accepted for column packing. For acceptable materials, a bonding lot number is assigned and all test data on the underlying silica and the bonded product are retained for future reference.

YMC … The Expert´s Choice.
