Welch Preparative Column uses the same packing materials as does analytical column, to ensure the best reproducibility of analysis and preparative scale. Special packing techniqueand stainless modular column tube ensure the stability of column bed. The theoretical platenumber for 10um column is greater than 35000/m; for 5um column, it is greater than 75000/m.and the peak symmetry is around 0.95~1.20.

Better Column Efficiency and Tailing

Better Separation Efficiency, Easier for Linear Amplification

Generaly, optimization of separation and purifcation process is done on the analytical column at frst. Same packingmateridls used in analvtica and purifcation process ensures the stability during linear amplifcation.

 Perfect Separation with Different Dimensions
