General Attributes
Triart C18 has excellent durability in difficult conditions such as acidic or alkaline mobile phases, and at temperatures above ambient. Triart users - in method development or in routine use - are able to better optimize their separations using conditions normally thought to be "out of bounds"... and achieve repeatable success.
This advantage carries over into mainstream applications as well. The combined effects of pressure, temperature, and pH take their toll on conventional columns. Triart can be expected to outlast conventional columns by a factor of 10x or more.

Homogeneous and Uniform Particles
YMC utilizes microreactor technology to produce high quality and highly uniform base hybrid spheres. Particle uniformity and homogeneity result in low operating pressure.
The uniformity of the base material also leads to highly reproducible surface modification (i.e., synthesis of the C18 bonded phase), which is essential to column-to-column and batch-to-batch reproducibility.

YMC Triart C18 exhibits very narrow, balanced, and tight control of pore size distribution. This results in sharp, well-controlled peak shapes, as well as high reproducibility of peak shape and elution behavior.
