Donot rinse the following columns
because they are either partially or not bonded:
Rtx-2330, Rt-2330, Rt-2340, Rt-ßDEX, Rt- DEX, Rt-TCEP &Micropacked
Restek's chemists have found that amixture of 60%methanol, 20%DI H
2
O, and 20%
methylene chloride (i.e. magicmix) is ideal for rinsing and cleaningmost bonded
stationary phases. (Do not use thismixture unless these solvents are recommended for
rinsing.) Themethylene chloride tends to swell the polymer which allows themethanol/DI
H

O to deeply penetrate into the swollen polymer lattice to remove polar contamination.
