The new Q-Col SpheripakTM HPLC silica has been specially developed to replace Waters SpherisorbTM one of the most popular packings on the market today.
Every parameter of the material has been evaluated to confirm total correlation between the two materials and the results of rigorous testing by users in many different fields confirm the excellent results obtained by using Q-Col SpheripakTM
Our strictly controlled manufacturing processes have been specifically designed to ensure the maximµm reproducibility and efficiency of every Q-Col SpheripakTM HPLC column.
We are so confident your Q-Col SpheripackTM column will work in an identical manner to the equivalent WS column - we guarantee it! If you are dissatisfied in any way with it comparative performance we will refund the price you paid.
The table below shows the comparative physiochemical characteristics between the Q-Col SpheripakTM and WS materials.
