What are the storage conditions for the IC-Pak Cation M/D 3.9 mm x 150 mm column (WAT036570)? - WKB192757

ENVIRONMENT

• IC-Pak Cation M/D (monovalent/divalent)
• Column storage

ANSWER

For short-term storage, leave the mobile phase in the column with the column connected to the system.

If the column will not be used for more than 72 hours, store it in 20:80 acetonitrile/water (v/v), replace the end plugs, and return the column to its box.

ADDITIONAL INFORMATION

When storing columns:

DO NOT store the column in methanol or methanol-containing solutions. Over time, methanol causes significant decreases in cation retention times. To prevent growth of bacteria, fill with 20:80 acetonitrile/water (v/v), replace the end plugs, and return the column to its box.

DO NOT allow the column to dry out. Allowing the column packing to dry out can result in poor chromatographic performance.

Store at 15 to 35 °C. Freezing during storage degrades performance.
