CN Flash Column, Chromatography Columns Supplier

Description

Description of CN Flash Column

The CN Flash Column from Hawach Scientific is packed with a bonded cyano functional group on an ultra-purity silica substrate. The polarity is between silicone gel and C18. CN flash chromatography column can be usually used for both normal and reversed phase flash separation. The scope of chromatographic applications.

Advantages of CN Flash Chromatography Column

Good compatibility with most flash systems;
The cartridge is available for 4g, 12g, 25g, 40g, 80g, 120g, 220g, 330g, 1600g, 3000g, etc.;
Medical PP-grade tubes provided high compatibility and flexibility and free leakage;
The column with standard Luer-Lock end fittings with perfect compatibility with most of the flash system;
Ultra-pure and high-efficiency bonded silica with CN stationary phase;
A column with a tight particle size distribution;
Multiple pore sizes and sample sizes for varieties of applications need;
Highly compatible with most flash chromatography systems.

Features of CN Flash Chromatography Column

Ultrapure normal phase silica basic column;
Standard Luer connection;
Superior compatibility with most flash systems;
Medical PP cartridge ensures excellent compatibility with solvents;
Super clean PE frit ensures the mobile phase passes through without extractable;
Spin-welded and allow the column for a higher pressure of up to 400 psi;
The cartridge’s maximum operating pressure is 200 psi.

Applications

Ideally used for separation of normal and reversed-phase flash chromatography.

Compared with traditional reversed-phase C18, and C8 chromatography columns, the Spherical CN Flash Columns have weaker hydrophobicity. For some compounds that are strongly retained on C18 and C8 columns, the rapidity separation can be achieved without adjusting the organic phase ratio.

CN flash column has multiple retention mechanisms: the cyano group on its surface will have a strong dipole-dipole interaction with polar compounds, while the propyl chain will provide a hydrophobic effect, giving it unique selectivity and broadening.
