Pack your own LC/MS Capillary Columns.
Pressure Injection Cells
These Column Packers ~ or Pressure Injection Cells as they are also called enable controlled dispensing of small-volume liquid samples. Using high pressure, the pressure injection cells have proved invaluable for two applications: densely packing nanobore capillary columns with solid-phase particles; and precisely infusing microliter samples directly from microcentrifuge tubes into mass spectrometers without additional transfers, wasted sample, or contact with metallic surfaces which adsorb some negatively charged molecules such as peptides with phospho or carboxy groups.
The Pressure Injection Cell holds 1 mL and 2 mL micro-centrifuge tubes as well as 12 x 32 mm glass vials in its central chamber (as shown at right). The assembly can be used on a typical magnetic stirrer, e.g. to keep particles in suspension. The Pressure Injection Cells accept various sample tubes, including 0.5 mL, 1.5 mL, and 2.0 mL microcentrifuge tubes and 12 mm diameter glass vials. The cell needs to be connected to a bottle/tank of compressed gas, such as Helium or Nitrogen. Packing capillary columns requires several hundred to about 1000 psi or sometimes more, and mass spectrometer injections typically require a few hundred psi. This unit is rated for a 2500 psi. 8500 psi units are available.
