The Birth of UG |
|
|
UG stands for "Ultra Grade." The packing
material is produced from high-purity silica with fine polymer coating achieved
by Shiseido's unique surface treatment technology. The UG series includes types
of various different functional groups to make full use of excellent separation
characteristics.

Low-polarity UG
Series |
|
|
The non-polar surface
allows quick and sharp elution of polar compounds. Since various functional
groups are supported, the retention and selectivity can be varied by replacing
the column, even under the same mobile phase. The UG80, the type of large
retention and high loadability, is also available, suited for preparative use,
too.

Features
|
|
|
- Sharp elution of basic, coordinating,
and acidic compounds with no tailing. Quick and sharp elution of polar
compounds.
- Low column pressure
→Narrow particle diameter distribution by
extremely precise
classification
- Extended pH range
→Polymer coating technology allows the pH
range 2-10. Excellent durability.
(NH2 : pH 2 to 8,
SCX: pH 2 to 7).
- Excellent lot reproducibility
→Validation-supporting silica ensuring
stable quality
through strict manufacturing control.
- Supporting GLP/GMP
→Certificates attached to C18UG120S5 (i.d.: 3.0, 4.6 mm),
C18UG80 (i.d.: 4.6 mm), and C18UG120V
(i.d.: 2.0, 1.5, 1.0 mm)
- Grades for preparative use lined
up
→UG120 (particle size: 5, 20, 30 µm) and
also UG80 (Particle size: 5, 20 µm) optimum for preparative use with high
loadability
- Complete lineup of functional
groups
- Full range of column sizes
→A complete lineup from microcolumns of 0.3
mm i.d. to preparative
columns
