Waters launched two columns this week for use with its liquid chromatography platforms. The Acquity UPLC HSS T3 columns are aimed at separating small, water-soluble, polar organic molecules via reversed-phased UPLC technology, the company said in a statement. The columns feature new 1.8 micron silica particles which the company said are the only 100 percent silica particles designed specifically for 15,000 psi/1,000 bar applications. The columns are available in 2.1 mm ID columns with lengths of 50 mm and 100 mm. Additional configurations are expected to be added before the end of the year.
Waters also introduced its Atlantis T3 HPLC columns this week. The T3 bonding technology “combines longer column lifetimes at low pH and improved peak shape for amine-containing bases at pH 7 with superior polar compound retention and 100 percent aqueous compatibility,” the company said. The columns are available in 3, 5, and 10 micron particle sizes in various lengths and dimensions.
Though the two columns are built on different particle substrates, methods can be moved from HPLC to UPLC because both LC columns utilize the same T3 bonding and endcapping process, Waters said.
