Maintenance of HPLC Columns
Hawach has established the complete operating procedure for the management and maintenance of HPLC columns, which is beneficial to keep performance and prolong the lifetime of columns.
Hawach HPLC columns are all tested to verify quality and performance, and shipped in the testing solvent to avoid physical damage. When not in use, the HPLC column should be washed out with a suitable solvent or combination of solvents, unless otherwise specified. Additionally, never store columns with buffers or iron-pairing reagents, and better store in dehydrated n-Hexane or isopropanol.
