KB series HPLC columns are packed with type-B ultrapure silica particles (purity > 99.999%) with metal content less than 10 ppm. The silica particles have been specially treated to eliminate micropores. Proprietary packing technology further enhances uniform column media distribution to minimize channeling effects. We have wide selection of bonded phases including C18, C8, C4, CN, NH2, CN, and phenyl-propyl, all double end-capped to further minimize tailing. In addition, KAQ-C18 (100% water compatible) and bare-silica HILIC are both available. The entire bonding, end-capping and packing process is strictly controlled and monitored, to ensure excellent performance, long lifetime, and exceptional batch-to-batch reproducibility.
