1.Fast balance，Only 1-3 min can achieve a balance

2. high-flowrate，low-pressure，the maximum possible flow velocity of 9mL/min，the reaction pressure only more than 100 bar flow、cut-off”are Never going to happen.Long column lifetimeand hard to be  polluted by impurity

3.The phenomenons of  “Stigma collapse”、“column bed short

4.  The separation is improved Through the change in velocity

5.  The column efficiency is equivalent to that of 3.5 u m particle size column

6.  The total porosity is above 80%
