Waters, 186006170, XSelect  HSS  C18 SB XP Column, 100 Å, 2.5 µm, 4.6 mm X 75 mm, 1/pkg

The XSelect HSS C18 SB column is a low coverage, unendcapped C18 phase used for low pH separations that contain complex mixtures of basic and non-basic compounds. XSelect HSS C18 SB columns give you alternative analyte selectivity compared to most modern, high coverage, fully endcapped C18 stationary phases. Packed in ultra-low dispersion hardware, 2.5 µm eXtended Performance [XP] columns enable exceptional separation performance, robustness and throughput for HPLC assays while enabling a seamless transition path toward UPLC adoption.

Additional Information
XSelect HSS C18 SB XP Column, 100 Å, 2.5 µm, 4.6 mm X 75 mm, 1/pkg For low pH separations, including intricate blends of basic and non-basic chemicals, the XSelect HSS C18 SB column is a low coverage, non-end-capped C18 phase. In contrast to the majority of contemporary, high coverage, completely end-capped C18 stationary phases, XSelect HSS C18 SB columns offer alternative analyte selectivity. A seamless transition path to UPLC adoption is made possible by the inclusion of 2.5 µm eXtended Performance [XP] columns in ultra-low dispersion hardware, which provides superior separation performance, resilience, and throughput for HPLC tests. Several particle technologies are needed to handle complex samples and enable a complete chromatographic analysis of various food types and other substances. Waters has created a wide range of laboratory equipment, including columns that make use of unique, distinctive, and exclusive particle technologies, to guarantee excellent operating stability in your lab. You can get around any chromatographic challenges by using properly selected ligands to complement the CSH and HSS technologies in Waters products. Waters' HSS—High Strength Silica technology was used to construct the XSelect HSS C18 SB Column, which was developed to improve the chromatographic performance of "Ethylene Bridged Hybrid" (BEH) and "Charged Surface Hybrid" (CSH) particles. The XSelect HSS C18 SB Column's properties let it withstand UPLC pressures, enabling it to give additional advantages in your system, including different selectivity and greater polar compound. This makes it fully scalable and transferable to UPLC separations.

FAQ
What Causes My LC System To Always Stop Down? To enhance system security, safeguard the columns and equipment, and assure system safety, HPLC pumps and systems come with an overpressure setting. The pump may stop working in order to safeguard the LC system if your system is operating at too low a setting or there is too much back pressure. Other factors could include the need for line cleaning or the removal of debris that has accumulated or crystallized and is obstructing or choking the system.
