Chromenta KB and KAQ

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. KB series HPLC and UHPLC columns with the same bonding chemistry for easy scale up in particle sizes of 3um, 5um, and 10um.

**Chromenta KB and KAQ Phases -** available in 3, 5, and 10um particle sizes, 120A pore size, and 320 m2/g surface area
