SKU: 176003147 CORTECS C18 Column, 90Å, 1.6 µm, 2.1 mm X 50 mm, 3/pk
CORTECS C18 Columns are general purpose, high-efficiency columns based on a solid-core particle that offer balanced retention of acids, bases and neutrals at low and mid-range pH.
CORTECS Solid Core C18 Column, 90Å, 1.6 µm, 2.1 mm X 50 mm, 3/pk
Leverage the power of the sub-2-µm to deliver outstanding results, whether you are trying to resolve complex mixtures or maintain resolution, using the CORTECS Solid Core C18 Column.
The CORTECS Solid Core C18 Column is a vital piece of lab equipment that guarantees higher column efficiency. This is because the solid-core particles improve performance by lowering each of the three terms of the van Deemter equation [HETP= A + (B/v) + C*v]. The A term is lowered as the solid-core particles pack more uniformly. The lower particle porosity of the solid-core particles reduces axial diffusion, which in turn lowers the B term. The C term is lowered as radial temperature gradients are diminished as solid-core particles improve heat transfer.
When compared to fully-porous particles of a similar size, solid-core particles hold the potential for higher efficiency owing to the dual nature of their morphology. Waters has made this theoretical potential into a reality with the CORTECS Solid Core C18 Column by using unique, ultra-low dispersion column hardware and proprietary optimal packing equipment and methodologies.
All Waters equipment is manufactured to the highest standards under strict and controlled environments to ensure that you receive only the best quality products.

You may also be interested in the CORTECS Solid Core C18 VanGuard Pre-column, 90Å, 1.6 µm, 2.1 mm X 5 mm, 3/pk. You can use the VanGuard Pre-column to enhance the life of your analytical column. This is because the VanGuard Pre-column protects the analytical column by removing all chemical and particulate contaminants from the mobile phase. This results in your analysis being accurate, precise, and reliable every time.
How Do You Minimize Band Spread Volume?
In chromatography, band spreading refers to the measurement of the system dispersion, which impacts the chromatographic performance. Both system band spreading and chromatographic performance can be immensely impacted by the internal tubing diameter and fluidic connections. This can be countered and minimized by using larger tubing diameters as they cause excessive peak broadening and reduced sensitivity.
