Description

Kromasil Classic 100 Å family of products is used to separate and purify molecules of up to about 10,000 Da.

• Kromasil™ C18 HPLC column involves a silica-based packing.
• The reduced levels of Na, K, Ca, Fe, Al, and Mg make the column useful for polar compounds, which tend to interact with the silica surface.
• Reverse phase (RP) HPLC columns are advantageous in ensuring high precision data, they are widely available commercially and are easy to use and less time-consuming.
• Two main approaches one should consider before choosing a RP column are, firstly characterising physiochemical parameters of the packing material such as 1% carbon load, surface area, pore size, particle size and pH.
  • These are some of the important parameters important to control the quality of the column.
• Second approach is based upon the chromatographic and statistical evaluation of the retention behaviour for a large number of compounds.
• Kromasil C18 columns are basically RP columns made up of silica-based monomeric type reversed-phase packing material.
