by GRACE
One Platform for UHPLC, HPLC and PREP
Separate complex samples with excellent resolution with VisionHT high performance columns. They are available with 1.5, 3, 5 and 10μm particle sizes and six different phase selectivities spanning the full polarity spectrum. The same base silica and bonding chemistries are used across all particle sizes therefore offering simple method transfer between UHPLC, HPLC and preparative systems.
For isomeric separation of non-aqueous compatible compounds by absorption chromatography.
