Linear gradient with a 2%/min rate of change with a flow rate of <0.5mL/min. Linear gradient with a 2%/min rate of change according to flow rates in table 2 (below).

1) Theoretical plates listed are based on smallest particle size listed.
2) High-temperature columns (HT) are shipped with ODCB (o-dichlorobenzene) as standard shipping solvent.
3) Dichloromethane and dichloroethane are not available for G1000 pore size columns.
4) See Table 1 (below) for available shipping solvents
5) After switching to a very polar solvent such as acetone, switching back to a nonpolar solvent is not recommended.
