1. Introduction

Diamond S is a strong cationic resin. Compared with SP Bestarose FF, it has a higher dynamic capacity at high flow velocity. The resin used for the resin is highly cross-linked rigid agarose, which can be adapted to high flow velocity operation, and its physical and chemical properties are stable. During purification and cleaning regeneration, the resin load and various properties are not affected by external buffers. The impact is more suitable for large-scale industrial production. Diamond S has the following characteristics:

High flow velocity, large volume of processing capacity, short operation cycle, improve productivity

High rigidity matrix, high pressure resistance
