|
The Whatman bulk silica media is used for low pressure columns. Same base silica and chemistries as those used for Whatman TLC plates. Particularly useful for scaling up separations optimized by TLC. In addition, Whatman offers an all-purpose media for general column chromatography. Applicable for preparative low pressure column separations scaled up from Partisil analytical HPLC columns.
Features and Benefits
- High resolution
- Good flow characteristics
- High surface area
