Waters Cortecs Columns

Waters Corporation has introduced Cortecs Columns, a family of 1.6 µ solid-core UltraPerformance LC columns. The columns are said to bring higher efficiency to chromatography, allowing laboratories to produce greater amounts of information faster with every chromatographic separation. Available in C18, C18+ or HILIC chemistries, they are offered in 30 column configurations.

Cortecs C18 Column is a general-purpose, high-efficiency, reversed-phase column offering balanced retention of acids, bases and neutrals at low- and mid-range pH. Cortecs C18+ Column is a general-purpose, reversed-phase column with a positively charged surface that delivers good peak shape for basic compounds at low pH. Cortecs HILIC Column is designed for the retention of extremely polar analytes while offering orthogonal selectivity versus C18 columns.

The column particles feature a solid, impermeable silica core encased in a porous silica outer layer where the interactions between the stationary phase and the analytes occur. When used together with the low-dispersion Waters Acquity UPLC, UPLC I-Class and UPLC H-Class Systems, the columns offer very high levels of performance.
