The Principle Of Flash Column

Flash column is usually used for the chromatography experiment to separate the complicated compounds by pressurizing air.

The hot air enters the stirring, crushing and drying chamber from the bottom of the dryer at a suitable spraying speed from the inlet pipe, which produces strong shearing and blowing. At the bottom of the dryer, larger and wet granules are mechanically broken under the action of the agitator, and particles with lower moisture content and smaller granularity are entrained by the rotating airflow to rise, and are further dried during the ascent. Because the two phases of gas and solid are rotating, the inertia of the solid phase is greater than that of the gas phase, the relative speed between the two phases of solid and gas is relatively large, and the mass and heat transfer between the two phases is enhanced, so the machine has high production intensity.

Hawach flash column will provide you different types of flash column. If you have any question for our product. Don’t hesitate to contact us.

Types of HAWACH Flash Column
HAWACH flash columns fall into the following three series: StarFlash series: silica gel column only, this series can be divided into standard and advanced sub-categories. Advanced silica has higher purity and better quality.

PureFlash series: silica gel construction and phase column. For example, C18(spherical inlet and irregular home-made), C4, C8, NH2, CN, HLIC, and oxide which are all imported fillers, corresponding to the high-end market.

DepuFlash series: silicone construction and phase columns, C18 (spherical and irregular),C8, NH2, CN, Phenyl, SAX, SCX, Diol are domestic fillers, corresponding to the low-end market.
