Insider TipSTORING PICOFRIT COLUMNS
If you need to store a PicoFrit® Column* for reuse on a later date, we recommend the use of a MicroTight® union, fitting, and sleeves to protect the tapered end of the column. Letting the column dry out for an extended period of time may render it unuseable. Protecting the tip end will allow you to store the column in a solvent-filled vial, beaker, or centrifuge tube.
Slip the distal end of the PicoFrit Column into the MicroTight sleeve, and oull through. DO NOT feed the column tip end first!
Pull the column further into the sleeve so that the tip is fully covered and protected by the sleeve. Tighten the fitting so that the column tubing is firmly held in place.
Place the column into a suitable vial or centrifuge tube and fill the container with suitable mobile phase. (The same composition used for column conditioning is recommended.) For best results, the column should be vertical, with the tip pointed sown. For long-term storage, the container should be covered with a suitable material to retard solvent evaporation. *This storage solution works only for PicoFrit Columns without a conductive coating. Storing coated tips and coated Self-Pack Picofrit Columns in the is manner will cause the platinum coating to separate from the emitter tip. |
