96:4 heptane:isopropanol

ADDITIONAL INFORMATION

If performing a reversed phase or HILIC method, the column must first be converted to the reversed phase of HILIC solvents, as follows:

1. Flush with 10 column volumes of 100% isopropanol.

2. Flush with miscible aqueous-organic mobile phase with no buffer for 10 column volumes. (Example: 50/50 water:acetonitrile)

3. Flush with initial mobile phase with buffer (if using buffer) for 10 column volumes.
