Waters, 186009409, Atlantis Premier BEH C18 AX Column, 5 µm, 2.1 x 150 mm, 1/pk

The Atlantis Premier BEH C18 AX Columns provide excellent retention for polar acidic analytes under reversed phase conditions. The reversed phase/anion-exchange mixed mode chemistry is stable from pH 2-10, and has complimentary selectivity to traditional C18 stationary phases, which is desirable when doing methods development.

Additional Information
Atlantis Premier BEH C18 AX Column, 5 µm, 2.1 x 150 mm, 1/pk Conventional reverse-phase chromatography may not be equipped to handle the separation and retention of polar acidic analytes, which is why the Atlantis Premier BEH C18 AX Column is here to help. This mixed-mode reverse-phase/anion-exchange column is uniquely suited to maximize throughput in LC separations. Scientists in the pharmaceutical and agricultural industries who work with surfactants are encouraged to use this product because of its capability to overcome the challenges set forth by amphiphilic compounds. How is the Atlantis Premier BEH C18 AX Column better suited for polar acidic analyte retention than other HPLC columns? For one thing, this BEH C18 anion-exchange can power through the retention and peak shape issues inherent in classic reverse-phase chromatography. The AX stationary phase included was developed by Waters because it helps to provide batch-to-batch reproducibility across your HPLC assays. What’s more, this LC column provides incredible stability thanks to its wide pH range. If you’re working with traditional C18 stationary phases, the Atlantis Premier BEH C18 AX Column can also come in handy. This in thanks to the complementary selectivity that the RP/AX stationary phase provides. The versatility doesn’t end there either, as the hybrid organic/inorganic particles inside the column are protected by MaxPeak High Performance Surface Interaction Technology. This prevents analyte loss due to interactions with stainless steel. What also makes this HPLC column better suited for reverse-phase/anion-exchange chromatographic separations is the unique ethylene-bridged hybrid (BEH) particle it contains. When compared to other traditional C18 column chemistry options, you’ll see that the BEH particle will aid you in the most difficult LC separations. Polar acidic analytes aren’t the only thing the Atlantis Premier BEH C18 AX Column can retain. Just look at the pH range of this Atlantis Premier HPLC column to see for yourself. This piece of lab equipment can operate between 2 and 10 pH with no concern about reproducibility. That kind of reliability makes Waters and the Atlantis Premier column line a top pick among scientists across the world. If you plan on using the Atlantis Premier BEH C18 AX Column across many different reversed-phase chromatographic separations, then you’ll want the maximum protection against losses in signal intensity. Buy a Atlantis Premier BEH C18 AX VanGuard FIT Cartridge to extend column lifetime to incredible lengths. Not only does this cartridge act as a guard against matrix contaminants, it can also keep you aware of any sample contaminants that might find their way into your LC assays. Retention of polar acidic analytes is just one of the many incredible things that Waters HPLC columns can achieve.
