Chromatography
paper
Whatman chromatography papers are the most widely used papers for
chromatography worldwide. This acceptance and usage reflects the purity,
high quality and consistency of Whatman papers. These qualities are
relied upon by chromatographers and essential to successful reproducible
chromatography. Whatman chromatography paper media are made from
specially selected cotton cellulose. They are rigorously quality
controlled for characteristics important to the chromatographer and to
ensure uniformity within the grade. The chromatography paper product
line includes standard cellulose and ion exchange grades.

Bulk silica media for column
chromatography |
|
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
