Flowrosil HPLC Columns

Flowrosil series HPLC column is designed for most LC method development, including a wide range of different phases (C18, C8,

Phenyl, C4, C1, and CN as reverse phases, and CN, Silica, NH2, and Diol as normal phases). All the phases are made from monomeric

organic silane to ensure exceptional batch-to-batch reproducibility and fast mass transfer. The different selectivity of primesil series

phases allows customers to select the best column to achieve optimal separation.

Characteristics of hybrid particles based Primesil H columns:

Wide pH range from 1.0 to 12.5

Silica particle properties of high mechanic strength and high efficiency and organic polymer properties of inertness and

resistance to alkali dissolution

Long column lifetime 5 times of similar product such as Gemini

Excellent peak shape for strong bases

Hybrid particles based flowrosil HPLC columns are designed for wide pH application, especially for high pH application because

of their unprecedented long lifetime at high pH. Hybrid particles based Flowrosil HPLC columns can be used at any mobile phase

composition and high temperature condition. They dont exhibit phase collapse even at 100% aqueous mobile phase condition.

Even under extreme conditions, the hybrid particles based Flowrosil HPLC columns will still exhibit excellent performance, making

hybrid particles based Flowrosil HPLC columns the most reliable solution for the most difficult separation.
