If you have determined, or suspect that the performance of your Pickering cation-exchange column or guard has degraded, consider our Repacking Service before purchasing a new column. Columns eligible for repacking include the Pickering amino acid, glyphosate and polyamine columns and their respective guards. Symptoms which suggest that it might be time to repack are peak broadening generally inferior resolution of peaks excessive back-pressure significant retention time shifts.
These malfunctions are usually the result of Irreversible contamination by proteins, oils, or other sample-borne materials backflow of post-column reagents into the column excessive flow rate, resulting in over-pressurization of the column the use of eluants containing a small percentage of organic solvent, e.g. methanol solid material blocking the frits. If you are not certain that the column or guard must be repacked, Pickering will test it for a service fee, freight or postage prepaid. This fee will be credited to any consequent repacking cost if tests indicate that repacking is needed.
For this repacking service,
Pickering will charge 75% of the current list price of
that particular column or guard.
Repacked and tested columns and guards carry the same warranty as new columns and guards.
Analytical columns will be repacked only one time. Each column has its own distinctive serial number, so we can advise you if your column has had this service before. Although guard columns are not serialized, we recommend a one-time re-packing for them, as well. But, no matter in what condition we find it, your old column will always have some value. If the column requires repacking, and the metal tubing and fittings are judged by Pickering to be damaged or corroded beyond re-use, then the entire column will be replaced. This exchange will amount to a "trade-in." Pickering Laboratories will accept your old column in trade, and charge 85% of current list price for its replacement.
Please contact Pickering for a Return Authorization Number and a cost estimate prior to returning the column for service or inspection. Payment will be requested under the terms applicable to your account. For most of our U.S. customers and international representatives, a Purchase Order Number will be accepted as the authorization to proceed with the service.
