YMC-Triart C18: A versatile hybrid silica-based HPLC column

Now available: YMC-Triart C18 1.9µm

YMC-Triart C18: a revolutionary, multi-layered, hybrid HPLC material which is manufactured using innovative "micro-reactor" technology. YMC-Triart's unique structure firmly tackles the challenges of high pH and high temperature separations.

YMC-Triart hybrid structure

An extremely narrow particle and pore size distribution results in a column with low back pressure and improved loadability. This, coupled with a tightly controlled hydrophobicity and silanol activity, makes YMC-Triart C18 a truly valuable tool for HPLC method developers.
"YMC have shown that when compared to other products on the market today, YMC-Triart C18 shows a narrower distribution which results in sharper peak shapes."
