ACQUITY UPLC Method Validation kits 

ACQUITY UPLC Method Validation kits provide three batches of chromatographic media (derived from different base particles) to assess the quality, reliability and consistency of your analytical method.

ACQUITY BEH Shield RP18 Columns

ACQUITY BEH Shield RP18 columns complement the ACQUITY BEH C18 and C8 phases and provide a necessary and powerful tool for HPLC method development. The embedded carbamate group in the bonded phase ligand provides alternate selectivity, especially for phenolic compounds compared to straight chain alkyl columns.

Embedded polar group reversed-phase LC columns contain stationary phases that combine the hydrophobicity of an alkyl ligand with the hydrophilicity of an embedded polar group. Features of embedded polar group columns include alternate selectivities as compared to alkyl chain LC columns, excellent peak shape for bases and aqueous mobile- phase compatibility. ACQUITY UPLC BEH Shield RP18 columns are designed to provide selectivities that complement the ACQUITY UPLC C18 and C8 phases.

ACQUITY UPLC Shield RP18 columns combine Waters patented Shield Technology with BEH Technology by incorporating an embedded carbamate group into the bonded phase ligand. The alternate selectivity and excellent peak shape from the embedded polar group ligand, when combined with the wide pH range and ultra-efficiency of the 1.7 μm BEH particle, provide a powerful tool for UPLC method development.

BEH (Ethylene Bridged Hybrid) Technology

In 1999, Waters launched the XTerra family of HPLC columns featuring first generation hybrid particle technology (HPT). HPT enabled XTerra columns to become one of the most successful column products in the history of Waters. In HPT, the best properties of inorganic (silica) and organic (polymeric) packings are combined to produce a material that has superior mechanical strength, efficiency, high pH stability and peak shape for bases. The first generation methyl hybrid particles of XTerra columns did not possess the mechanical strength or efficiency necessary to fully realize the potential speed, sensitivity and resolution capabilities of UPLC technology. Therefore, a new pressure-tolerant particle needed to be created. A new, second generation hybrid material was developed which utilizes an ethylene bridged hybrid (BEH) structure. Compared to the first generation methyl hybrid particle of XTerra columns, the BEH particle of ACQUITY UPLC BEH columns exhibits improved efficiency, strength and pH range. BEH Technology™ is a key enabler behind the speed, sensitivity and resolution of UPLC separations.

ACQUITY UPLC columns

ACQUITY UPLC columns are the most technologically advanced LC columns ever created and are the only columns designed, tested and certified to withstand the pressures of UPLC Technology. Based upon the highly efficient 1.7 µm Bridged Ethyl Hybrid (BEH) particles and 1.8 µm High Strength Silica (HSS) particles, these columns are the first and only columns that allow separation scientists to achieve maximum speed, sensitivity and resolution without compromise. The particles and chemistries of the ACQUITY UPLC column family were carefully chosen to produce the ideal combination of ultra-performance efficiencies, wide pH range and complementary selectivities. ACQUITY UPLC BEH columns and ACQUITY UPLC HSS columns are the only columns recommended for use with ACQUITY UPLC Systems.

There is more to creating a UPLC particle than synthesizing a small particle. Many HPLC particles do not possess the mechanical stability and structural integrity to withstand UPLC operating pressures (e.g., 15000 psi/1000 bar). Why is pressure tolerance important? In order to realize the efficiency gains of sub-2 μm particles, the ability to routinely operate at higher linear velocities (e.g., higher flow rates) is required. These higher linear velocities combined with small, sub-2 μm particles result in higher operating backpressures. Waters has created two highly efficient, pressure-tolerant UPLC particles: the 1.7 μm Ethylene Bridged Hybrid (BEH) particle and the 1.8 μm High Strength Silica (HSS) particle.

The first ACQUITY UPLC particle created was the 1.7 μm Ethylene Bridged Hybrid (BEH) particle. This second generation hybrid particle is one of the key enablers behind UPLC technology and is available in five column chemistries: C18, C8, Shield RP18, Phenyl and HILIC. Because this is a hybrid particle, a wider usable pH range (up to pH 1-12) makes method development faster and easier. BEH particles are also available in HPLC particle sizes (2.5, 3.5, 5 and 10 μm) in the XBridge family of HPLC columns, thus allowing seamless transfer between HPLC and UPLC separations.
