SunBridge

A hybrid column generally refers to a column that uses so-called hybrid silica (organic silica) particles, in which a certain proportion of ethylene bridges is applied to the silica gel skeleton (inorganic). Its main feature is said to be its high resistance to alkali.

However, the method of manufacturing highly alkaline durable columns is not limited to using organic silica. It is also possible to increase durability by ingenuity in surface treatment (end-capping) after the introduction of functional groups. For example, Prominert, which we developed in 2022, has high pH durability comparable to that of hybrid columns by applying an advanced inactivation method.

Prominert

The highest deactivation universal reversed-phase column for superior inertness and resolution across any HPLC system.

Prominert delivers high-efficiency separation at less than 20 MPa, combining exceptional pH durability, high retention, and lower operating pressure than hybrid-type columns. Available in C18 and Biphenyl phases, offering unique selectivity for compounds that are difficult to resolve on standard C18 columns.
