Piston pump syringe column method and device

A water solvated chromatography bed is packed into the distal end of a syringe barrel. The syringe pumping piston is modified to be flat to match the top frit structure (that is also flat). The piston pump is pushed into the syringe barrel until the piston is directly above the column top frit. The...

More Information
Summary:A water solvated chromatography bed is packed into the distal end of a syringe barrel. The syringe pumping piston is modified to be flat to match the top frit structure (that is also flat). The piston pump is pushed into the syringe barrel until the piston is directly above the column top frit. The pumping piston is moved forth quickly to dislodge entrained air in the bed. The piston pump moves directly above the resin bed with no air gap above the bed.
