CORTECS C18+ Column, 90Å, 1.6 µm, 2.1 mm X 150 mm, 1/pk
The CORTECS C18+ Column is a general-purpose, high-efficiency reversed-phase column whose positively charged surface delivers excellent peak shape for basic compounds at low pH. The column is designed on solid-core particles, which provide improved performance by lowering each of the three terms of the van Deemter equation. The A term is lowered as the solid core particles pack more uniformly, the B term is lowered as the solid core particles exhibit lower particle porosity, which reduces axial diffusion, and they lower the C term as their solid core improves heat transfer, reducing radial temperature gradients.
By simply raising the flow rate of the method, the CORTECS Solid Core C18+ Column enables you to increase your sample throughput with comparable or even better peak capacities. The unique column design and properties allow you to use a shorter column length compared to the original separation, while maintaining similar peak capacities. This can assist with a significant reduction in your overall lab operating costs.

You may also be interested in the CORTECS C18+ VanGuard Pre-column, 90Å, 1.6 µm, 2.1 mm X 5 mm, 3/pk; the CORTECS C18+ VanGuard Cartridge is designed to protect your analytical column and to extend its lifetime by removing any particulate or chemical contamination.
What Is The Best Way To Store The CORTECS Solid Core C18+ Column After Reversed-Phase And HILIC Use?
It is recommended to store the column in 100% acetonitrile for durations longer than four days. Store the column immediately after use in 100% acetonitrile for separations utilizing elevated temperature. Kindly do not use buffered eluents to store the column; if your mobile phase used contains a buffer salt, flush the column with 10 column volumes of HPLC-grade water followed by 10 column volumes of acetonitrile. If these recommendations are not followed, it could result in precipitation of the buffer salt in the column when 100% acetonitrile is introduced. Completely seal the column to avoid solvent evaporation and drying out of the chromatographic bed.
What Are The Pressure And Temperature Limitations Of The CORTECS C18+ Column?
This CORTECS C18+ Column can withstand pressure up to 18,000 psi (or 1240 Bar) and a maximum temperature of 45 degrees. It also has a pH range of 2 to 8. However, you should note that working at the extremes of pressures, pH, and/or temperatures will result in shorter column lifetimes and effectiveness.
