Flow Splitter adjustable, fully automatic!

flow splitter adjustable and fully automatic


   
   
   For the first time ever!
 
   The AS650 is the first fully automatic, adjustable 
   flow splitter for HPLC and LC/MS applications.









Input and output flow rates are entered via a keypad; data and status are shown on the digital display. Since the AS650 dynamically compensates for any deviation in the flow rate, it can also be used in pre-column split mode. The flow rate and split ratio remain constant during the gradient run. Fluctuations in the column back-pressure or changes in the viscosity of the mobile phase have no influence.

Used pre-column, the AS650 Flow Splitter is effective into the nanolitre range and when placed post-column it can be used for both analytical and preparative applications.

The AS650 does not require elaborate volumetric calibration, even in the range of 
100 nl/min.
