Spherical C18 Flash Columns

Description of Spherical C18 Flash Column

Hawach spherical C18 flash column is a preparative grade chromatography separation column product that has undergone rigorous mass determination. The particle size distribution of the Sorbent is very uniform, ensuring that the column maintains normal column pressure during the application.
The performance parameters of each batch of Hawach flash columns are strict control and testing to ensure high recovery and perfect reproducibility from batch to batch. A series of steps, such as uniform particle size, uniform pore size distribution, and Hawach’s unique bonding technology, ensure effective separation of the objective compounds of the Hawach flash column.

C18 reversed-phase separation columns are widely used in natural product extraction, pharmaceutical synthesis research and development, and biopharmaceuticals. If the polarity of your sample is too large and the Rf value is very close, the normal phase mode cannot be separated; the final product requires a purity of more than 98%, which cannot be achieved by the normal phase mode; samples with dissolution problems in normal phase conditions – the above situation may be considered The separation was performed in reversed-phase C18 mode. At present, the C18 column has become the reversed-phase column most frequently used by separation and purification researchers due to its mature packing technology and excellent separation ability.
