Waters ACQUITY Premier CSH C18 Column with VanGuard FIT, 130A, 1.7 um, 2.1 x 150 mm, 1/pk - 186009465

Waters™ ACQUITY Premier CSH C18 Column with VanGuard FIT, 1.7 µm, 2.1 x 150 mm, 1/pk

Product Number: 186009465

Specifications:

ACQUITY Premier CSH C18 Columns overcome peak shape asymmetry and poor loading capacity for basic compounds when using low ionic strength mobile phase. The surface charge enables fast column equilibration when switching from low to high pH mobile phases. MaxPeak High Performance Surface hardware technology significantly reduces unwanted analyte/surface interactions that can lead to poor peak shape and losses in signal intensity. The VanGuard FIT Column design protects the column from contaminants and increases column lifetime.

UPLC Column Protection – VanGuard Pre-Columns

Contamination resulting from the analysis of samples present within complex matrices, or that are particulate-laden, may result in reduced column lifetime if not properly addressed. VanGuard™ Pre-Columns are ideally suited for the physical and chemical protection of ACQUITY UPLC Columns. Directly compatible with UPLC pressures up to 18,000 psi [1241 bar], this ultra-low dispersion direct connect guard column is specifically engineered to preserve the lifetime of an ACQUITY UPLC Column without negatively impacting its separation performance.

CSH (Charged Surface Hybrid) Technology

The 1.7 µm Charged Surface Hybrid (CSH™) particle is Waters third generation hybrid particle technology. Based on Waters Ethylene Bridged Hybrid (BEH) particle technology, CSH particles incorporate a low level surface charge that improves sample loadability and peak asymmetry in low-ionic-strength mobile phases, while maintaining the mechanical and chemical stability inherent in the BEH particle technology.

The advantages of CSH Technology UPLC chromatography columns include:

• Superior peak shape for basic compounds
• Increased loading capacity
• Rapid column equilibration after changing mobile-phase pH
• Improved batch-to-batch reproducibility
• Exceptional stability at low and high pH

CSH particle technology is also available in HPLC particle sizes (3.5 and 5 µm) in the XSelect™ family of HPLC columns, enabling seamless transfer between HPLC and UPLC® technology platforms.

ACQUITY Premier CSH C18 Columns

• Universal column choice for UV and MS applications
• Suitable for a broad range of compounds
• Alternate selectivity to BEH C18
• Exceptional peak shape and increased load capacity
• Suited for basic compounds at low pH

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.
