Solid core particles for higher efficiency
It was originally thought that the high efficiency of a 2.7 μm solid core particle column was due to the fact that solid particles had a shorter diffusion path than fully porous particles, resulting in faster mass transfer kinetics. However, for low molecular weight analytes, the high diffusion rate has very limited improvement in column efficiency. Current research shows that solid core particles can improve chromatographic performance by reducing three parameters in the Van Deemter equation.
Achieve new efficiency standards
Compared to fully porous particles of similar particle size, solid core particles are more likely to achieve higher efficiency due to their morphological characteristics. To achieve this theoretical efficiency, you need to work with the right column hardware and the best column packing technology. With years of leading UPLC column production experience, Waters has set a new standard for UPLC column efficiency with ultra-low-diffusion column hardware and exclusive column packing technology, along with new CORTECS particles.
Improve the peak shape and loading of alkaline analytes with CORTECS C18+ columns
Based on the surface-charged hybrid particle technology (CSHTM) successfully launched by Waters in 2010, a small amount of positive charge is applied to the surface of the particle, and a low ionic strength mobile phase (such as formic acid) can be used, and the basic compound can still be excellent. Peak shape and load.
