Description

Description

Starlab Scientific Co., Ltd C18-Alkaline with high purity silica gel is embedded in aqueous groups, making it aqueous. aqueous groups replace a large number of siloxyl sites, effectively preventing the interaction between alkaline substances and silicones.
Due to the embedding of aqueous groups, the selective and traditional anti-phase C18 and other chromatographic columns have obvious differences.

Advantage

Unique bonding and end-capping technology
Optimization of chromatographic parameters such as surface area and carbon content
Excellent balances retention, separation, and pollution resistance
Average sample size & pore size make well flow rate
Perfect peak shape & high peak volume
Pure silica gel ensure high mechanical strength and high specific surface area
Spherical silica gel, good stability, improve separation efficiency and reproducibility
Ultra-dense bonding and double-ended ensure long life
Basic, acidic, and neutral compounds make excellent peak shape
Wide range of pH with long service life
Used with most HPLC instruments (Agilent, Biotage, Grace etc)

Features

1. Embedded in the aqueous group
2. Aqueous groups replace a large number of siloxyl sites, which can make analysis of alkaline substances can obtain the perfect peak shape
3. High water phase ratio can be used to stabilize the flow
4. Quick separation of similar samples
5. pH Range: 1.5-10.0

Applications

1. Containing alkaloids ingredients Chinese medicine
2. Be separated by the mobile phase to quickly separate similar samples
