UHPLC Guard Column Cartridge Ultisil HILIC, 4 x 5 mm

Welch also offers Ultisil® UHPLC (1.8 µm) columns. With high column efficiency and good lot-to-lot reproducibility, Ultisil® UHPLC can generate high quality data, decreasing the probability of repeated sample analyses while reducing the consumption of solvent at the same time. Ultisil® UHPLC series offer a variety of bonded phases, specified guard columns and pre-columns for the users to design and realize faster and more environmentally friendly chromatography applications with higher resolution.

• Ultra resolution: same resolution as or better than that of conventional column which has more packing materials
• Ultra speed: UHPLC offers more information per unit time and higher speed owing to its smaller particles.
• Sensitivity: higher N, narrower peak width (W), higher peak height. The system sensitivity of 1.8 µm UHPLC is 70% and 40% higher than that of conventional column of 5µm and 3.5µm packings, respectively.
