HAISIL HL “high load” columns are intended for applications requiring maximum loading and selectivity. The high surface area permits high bonded phase loading yet the monofunctional bonded phase and the absence of micro-pores eliminates the problems that plague many of the so-called “high capacity” columns currently on the market. The Type B silica backbone is pure, robust, and stable under harsh conditions. Users report satisfactory lifetime when used for prolong periods at pH as high as 9.
