by Bonna-Agela Technologies
Using the silica of high-purity and high mechanical strength, the Promosil C18s are made with high-purity monosilane through Agela Technologies’ well controlled bonding process. They have high surface bonding coverage and completely capped. The carbon content is as much as 18%. They are stable at pH range 1.5-9.0 showing good peak shape for acidic and basic compounds. They have excellent tolerance of contamination and long life-time. They are the best choice of high performance-to-cost value.
