HOW TO IDENTIFY WHICH T3 COLUMN IS RIGHT FOR YOU
Is the ability to easily transfer methods to other platforms
most important?
Are faster run times and improved resolutions
most important?
Is isolating and purifyingpolar compounds most important?
[ T3 COLUMNS ]
Retaining Polar CompoundsT3 columns are ideal for polar compound retention
What is a T3 column?T3 reversed-phase columns are designed for separating polar compounds. An optimized particle pore size and C18 surface concentration enables reliable operation with 100% aqueous mobile phases needed for retaining highly polar analytes. Waters® offers a full range of CORTECS® Solid-Core T3, XSelect® HSS T3/ACQUITY UPLC® HSS T3, and Atlantis® Silica T3 columns and method validation kit options based on your separations needs.

DID YOU KNOW?
Fully-porous packing materials such as Atlantis T3 and HSS T3,
exhibit higher retention, while the solid-core packing
materials used in CORTECS T3 is designed for maximum
e�iciency and peak capacity.

The higher e�iciency of the CORTECS T3 column provides faster runtimes while
improving resolution.
Atlantis T3 preparative columns outperform conventional C18 columns
for polar compound loading.
Because ACQUITY HSS T3 and XSelect HSS T3 di�er only in
particle size, transfer between columns and instrument
platforms is straightforward.
