Particle technology

YMC-Triart is a multi-layered material prepared from well-controlled particle formation technology which is adapted from micro-reactor technology. The recently developed production step results in truly narrow particle and pore size distributions!
With YMC-Triart, challenging pH and high temperature conditions are no longer a limitation to the day-to-day work in laboratories. Most importantly, due to its unique particle composition, a balanced hydrophobicity and silanol activity are achieved which makes YMC-Triart a ”First Choice“ column in method development!

YMC-Triart hybrid structure

Uniform spherical particles YMC-Triart C18 X-Bridge HILIC The new uniform spherical particle support is adopted for YMC-Triart C18. The particle is produced using micro-reactor technology in granulation process. This results in reduction of the back-pressure and leads to more reproducibility in surface modification. Low column back-pressure Column: 5 μm, 150 x 4.6 mm ID Eluent: acetonitriel/water or methanol/water Flow rate: 1.0 ml/min Temperature: 25°C The revolutionary production technique, adapted from micro-reactor flow technology, produces a multi-layered silcia/organic hybrid stationary phase, with outstanding narrow pore size and particle size distributions which result in low back pressures. YMC-Triart C18 is designed for use under many conditions. Elution with higher viscosity methanol (compared with acetonitrile), YMC-Triart C18 generates lower pressure (approx 30% lower than with conventional phases). Application courtesy of YMC Co., Ltd. Narrow pore distribution This figure shows the pore size distributions of some competitive materials. Compared with other products on the market, YMC-Triart C18 shows a narrower distributon which results in sharper peak shapes. Improved loadability Influence of injection volume on peak shapes solvent for sample acetonitrile injection volume 1.0 µl 1.5 µl 2.0 µl 3.0 µl Column: 5 µm, 50 x 2.0 or 2.1 mm ID Eluent: A) water/formic acid (100/0.1) B) acetonitrile/formic acid (100/0.1) 5% B (0-0.5 min), 5-100% B (0.5-2.5 min) Flow rate: 0.4 ml/min Teperature: 40 °C Detection: UV at 275 nm In order to prevent peak errors, there is the limit to the injection volume when the sample is injected in high elution solvents (such as acetonitrile). Compared with traditional columns, more than double the injection volume can injected into YMC-Triart C18 as a result of the extremely narrow particle size distribution.
