One of the main problems encountered in preparative HPLC is the wall effect due to the tube.

 

The parabolic shape of the sample shows that the speed is high in the middle and extremely low on the sides of the tube. This is shown on the chromatogram by a peak tailing and is a prejudice to the good productivity during a purification.

Annular injection system (A.I.S.)

AIS is a split-Flow injection system which allows the compensation of the wall effect of the conventional columns. The central flow/flow ratio can vary in order to obtain a perfect optimization of the Easy-pack performance.

One of the main advantages of AIS in regards to traditional columns is the tremendous increase of the loading capacity.
