CORTECS Shield RP18 Column, 90Å, 2.7 µm, 4.6 mm X 100 mm, 1/pk
In analyses where you require complementary selectivity to C8 and C18 stationary phases, leverage the CORTECS Shield RP18 Column. Because the lab equipment utilizes an embedded carbamate group in the bonded phase ligand, you are able to leverage it to get alternate selectivity, especially for phenolic compounds compared to straight-chain alkyl columns. When it is compared to fully porous particles of similar particle size, the solid core particle morphology of the CORTECS Column offers high efficiency and lower back pressures.
The CORTECS Shield RP18 Column is designed to be general-purpose and deliver high-efficiency results, providing crucial benefits through its versatility. The lab equipment is based on a solid-core particle that offers balanced retention of acids, bases, and neutrals at low and mid-range pH. These attributes result in the delivery of excellent peak shape for basic analytes, even at low pH.
Using the general-purpose CORTECS Shield RP18 Column, you can easily resolve complex mixtures or maintain resolution while increasing throughput. The column is able to deliver exceptional results as its solid-core particles give better 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, while the B term is lowered as the solid core particles exhibit lower particle porosity which reduces axial diffusion. They lower the C term as their solid core improves heat transfer, reducing radial temperature gradients.
With the CORTECS Shield RP18 Column, you can easily increase your sample throughput with comparable or even better peak capacities. This can be achieved by simply raising the flow rate of the method. The lab equipment also helps to reduce your lab operation costs as it provides the speed of analysis without impairing separation performance, giving you the ability to run multiple samples in the same amount of time.
Waters recommends that you also purchase the CORTECS Shield RP18 VanGuard Cartridge, 90Å, 2.7 µm, 3.9 mm X 5 mm, 3/pk, which is a piece of protective lab equipment designed to connect directly to your column and prevent harmful particles from reaching the mobile phase.
What’s the Difference Between C18 and RP18 Columns?
A C18 column is for a stationary phase, while the RP18 column provides alternative selectivity.
