Column chromatography in chemistry is the preparative application of chromatography. It is used to obtain pure chemical compounds from a mixture of compounds on a scale from micrograms up to kilograms using large industrial columns.

 
Advantages & Benefits:

• Selection of particle size to optimize efficiency.
• Large surface area to optimize the capacity.
• Consistent and reproducible retention times to allow direct scale-up from laboratory through process applications.
• Lot-to-lot consistency to assure reproducible performance.
• Bulk quantities for large-scale applications, no scale-up limitation, secured lots offered for process use.

Stationary Phase (Adsorbent)
The stationary phase or adsorbent in column chromatography is a solid. The most common stationary phase for column chromatography is silica gel & alumina. Also possible are ion exchange chromatography, reversed-phase chromatography (RP), or affinity chromatography. The stationary phases are usually finely ground powders or gels and/or are micro porous for an increased surface.
