hplc column protection
Upon Receipt Of The Column
• Verify the column you received is the column you ordered
• Check the column for physical damage that may have occurred during shipping
• Test the column immediately to verify quality and performance
• All columns are shipped in the testing solvent, unless otherwise specified
Each Phenomenex manufactured HPLC column is individually packed and tested to ensure outstanding column quality. Every column is supplied with its Test Chromatogram and a Specification Sheet that indicates testing conditions, operating parameters, column serial number and identity.
The warranty period begins upon receipt of the column. Testing is especially important if the column is to be placed in storage. Test the column using the same conditions in the test chromatogram. Use the formulas on p. 370 to determine column efficiency and peak asymmetry.
Chromatographic performance depends on the entire system, not just the column. Columns are QC tested using optimum conditions to minimize band-spreading from “Extra Column Effects.” See pp. 85-86 for HPLC Column Performance Check Standards. Most variations from the Phenomenex test data are due to extra column effects created by your system’s design (e.g., injector, flow cell, connecting tubing, etc.). If you have any questions regarding your test results or the column quality, or if there are signs of damage, contact your local distributor or Phenomenex immediately.
