Additional Information
CORTECS C18 Column, 90Å, 2.7 µm, 2.1 mm X 150 mm, 1/pk Get balanced retention of acids, bases, and neutrals at low and mid-range pH by using the Waters CORTECS C18 Column, which is a general-purpose, high-efficiency column based on a solid-core particle. By using the lab equipment, you can easily maximize efficiency for maximum resolution as its solid-core particle technology makes it an ideal piece of lab equipment to offer higher efficiency, while giving you increased resolution for analyzing complex samples when compared to fully porous columns. Increase sample throughput with comparable or better peak capacities simply by raising the flow rate of the method using the Waters CORTECS C18 Column. Its chemistry also enables the use of shorter column lengths compared to the original separation while maintaining similar peak capacities and providing faster re-equilibration time. Additionally, the column contributes to the reduction of cost of analysis and lab operations as you can run more samples at the same time and get results faster. This speed of analysis is offered by the CORTECS C18 Column without compromising separation performance. Waters adhere to strict manufacturing practices and standards at every step of the manufacture of the CORTECS C18 Column. The environment is tightly monitored and controlled to ensure that the analytical column is high quality, gives unparalleled reproducibility and consistent performance year after year. The CORTECS C18 Column allows you to leverage the power of the sub-2-µm to deliver outstanding results, whether you are trying to resolve complex mixtures or maintain resolution. The addition of the analytical column will give you a crucial, dependable piece of lab equipment that guarantees higher column efficiency due to the presence of the solid-core particles. These 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. Shop for lab equipment such as the CORTECS C18 VanGuard Cartridge, 90Å, 2.7 µm, 2.1 mm X 5 mm, 3/pk , which protects your analytical column and enhances its lifetime.

FAQ
How Is Pressure Affected By Particle Size? As particle size is reduced, back pressure increases at a rate that is inversely proportional to the square of the particle diameter. At the same time, the optimal mobile-phase speed, also known as linear velocity, increases with decreasing particle diameter.
