Waters Cortecs 2.7 micron columns

Waters has expanded its family of Cortecs columns with the 2.7 micron silica-based, solid-core particle columns. Designed for analytical scientists who need to maximise performance on their existing LC systems, Cortecs 2.7 micron columns run at low pressures while delivering high efficiencies. This gives the user the flexibility to use longer column lengths to improve resolution or higher flow rates to speed instrument analysis times and increase throughput.

Available in C₁₈+, C₁₈ and HILIC chemistries, the company offers the columns in 48 column configurations. The columns are fully scalable to Cortecs 1.6 micron columns for ultraperformance LC (UPLC), thus allowing separation scientists who currently run HPLC separations the ability to futureproof their laboratories and transfer or migrate their separation to UPLC.

C₁₈+ columns deliver good peak shapes for basic compounds and impart selectivity while being a low-bleed, formic acid-friendly option for LC/MS applications. C₁₈ columns are general-purpose, high-efficiency RP columns offering balanced retention of acids, bases, and neutrals at low and mid-range pH. They provide good resolution and retention for complex mixtures.

HILIC columns are designed for the retention of extremely polar analytes using hydrophilic interaction chromatography (HILIC). Additional benefits include increased mass spectrometry response and compatibility with direct injection of organic extracts from common sample preparation techniques, such as solid-phase extraction (SPE), liquid-liquid extraction (LLE) and protein precipitation (PPT).
