Column Packers – Pressure Injection Cells
Load your samples into the mass spectrometer without transfer loss or contact with metallic surfaces.
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. 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.
Features:
- Easy sample tube removal since the tube protrudes above the bottom section of the pressure injection cell.
- O-ring seal at interface ensures no leakage.
- Includes a 3-way valve for easy switching between pressurization and release of pressure.
- Three bolt system secures the cell, allows easy addition and removal of tubes / vials.
- Holds 0.5 to 2 ml microcentrifuge/Eppendorf tubes and 12 x 32 mm (glass) vials.
- Includes operator’s manual; 10 reusable ferrules for typical (380 µm outside diameter) capillaries (other ferrules are available); and 1.5 mL of Kasil and 0.5 mL of formamide and a cleaving tool for making your own frits.
- Warranty: 2 years parts and labor.
- 30 day money back guarantee.
Operation – How do Column Packers Work?
Operationally, the pressure injection cell is analogous to a straw in a juice box. As you apply pressure in the box, the juice will be forced out through the straw. Likewise, the pressure injection cell is connected to pressurized gas, typically in a tank. A 0.5 to 2 mL tube containing the sample liquid is placed in the base of the pressure injection cell. A capillary is then placed through the ferrule in the cap and down into the sample tube. When packing a capillary, a frit assembly is placed at the distal end of the capillary to prevent particles from exiting and the entire pressure injection cell is typically placed on a stir plate. By regulating the gas pressure, you can adjust the flow rate of the sample into the capillary.
