Typical Applications

Multicolumn Selection

Advantages

•

Increase productivity

•

Higher instrument up- time

Quickly change between up to eight different stationary phases for different 
applications, or use identical stationary phases in columns with different 
dimensions for either faster run- times (short columns) or higher resolution (long 
columns) or for loading studies with different internal diameters.
