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.
Features
-
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
Hardware Features
- New design
- Low dead volume
- New special frit
Packing Materials Features
- High efficiency 1.8μm particles
- High column efficiency and excellent strength
- Variety of bonding chemistries
- Stable column bed, highest pressure: 15000psi
Column Packing Features
- Unique column packing technique
- Withstand ultra-high pressure of UHPLC instruments
