Increasing sample throughput, achieving unmatched resolution, and improving analyte sensitivity are priorities for your separation goals. With Waters ACQUITY UPLC Columns, you can meet all your method requirements and substantially reduce your analysis time and cost-per-sample.
Waters ACQUITY UPLC Columns’ sub-2-µm particle chemistries enable chromatographers to harness the separation efficiency improvements at increased flow rates of ultra-performance liquid chromatography (UPLC) technology, thereby improving analyte resolution and sensitivity as well as business productivity and profitability.
ACQUITY UPLC BEH 1.7 µm fully porous columns provide superior analyte peak shape, efficiency, and chemical stability to any separation. ACQUITY UPLC BEH Columns are available in both reversed-phase and HILIC separation modes, with chemistries that provide selectivities for a wide range of compounds. With the ruggedness to operate at extreme pH conditions, ACQUITY UPLC BEH Columns enable the separation scientist to use a wide pH range to influence retention, selectivity, and sensitivity for ionizable compounds.

ACQUITY UPLC CSH™ 1.7 µm fully porous columns provide superior peak shape for basic analytes when using low ionic strength acidic mobile phases (e.g. 0.1% formic acid). With CSH Technology, the controlled low-level positive surface charge provides exceptional peak shape for basic analytes which can be achieved without the use of ion pairing reagents. Typically reversed-phase bonded phases have poor peak shape for basic compounds in formic acid even at analytical mass loads. Built on the rugged Ethylene Bridged Hybrid (BEH) particle, ACQUITY UPLC CSH phases can withstand the toughest operating conditions.

ACQUITY UPLC HSS 1.8 µm fully porous columns provide expected silica particle-like performance to the UPLC family. The HSS particles’ high surface area, and lower pore volume provide increased retentivity over the hybrid particles. This robust particle technology is available in five uniquely different bonded phases, which truly maximize the selectivity space. The wide array of bonded phases associated with ACQUITY UPLC HSS Columns enable traditional hydrophobic reversed-phase interactions along with dipole-dipole interactions, aromatic interactions, and hydrogen bonding interactions.

Reversed-phase bonded phases typically have poor peak shape for basic compounds when using formic acid, even at analytical mass loads. However, ACQUITY UPLC CSH Columns are the exception. These rugged UPLC Columns provide superior peak shape for basic analytes with formic acid or other low ionic-strength, acidic mobile phases. The controlled, low-level, positive surface charge bonded to the ethylene-bridged hybrid (BEH) particles provides excellent peak shape for bases—without the need for the use of ion-pairing reagents.
