What is the long-term storage solvent for the Carbohydrate Analysis column (WAT084038)? - WKB226887

ENVIRONMENT

• High Performance Liquid Chromatography (HPLC)
• Hydrophilic interaction chromatography (HILIC)
• Column care and use
• Carbohydrate Analysis

ANSWER

100% acetonitrile

ADDITIONAL INFORMATION

For periods of three days or less, store this column in 80:20 water/acetonitrile (or similar HILIC mobile phase).

For periods of more than three days, store this column in 100% acetonitrile.

Note:

If this column is kept in the presence of water or methanol for long-term storage, the NH₂ ligands can hydrolyze off of the particles, which can lead to selectivity changes.
