Waters introduced CORTECS Columns, a new family of 1.6 micron solid-core UltraPerformance LC Columns. Available in C18, C18+ or HILIC chemistries, Waters offers the columns in 30 unique column configurations and is making them available for shipping worldwide. Waters introduced the new columns at HPLC 2013, the 39th Annual Symposium on High Performance Liquid Phase Separations and Related Techniques. CORTECS 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. The three CORTECS chemistries and their intended uses are:

• 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 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.
