Excellent resolution without adsorption and tailing

YMC-Triart series 1.9 µm's innovative surface modification technology results in excellent peak shapes even for the basic and coordination compounds that often exhibit adsorption or tailing shapes on other UHPLC columns. Thus, its quantitative capability is sufficient, and decreases the risk of missing unknown constituents. YMC-Triart series stands head and shoulders above any other columns in quantitative capability.
