What are the basic differences in the function of the MultiSep® and the MycoSep® columns?
The main difference is the format: MultiSep® columns are columns in syringe format. The extract runs through, the speed could be varied by applying vacuum or pressure. The MycoSep® is a simple 10-second clean up format. The MycoSep® clean up column is pushed into a test tube (containing the extract), forcing the extract to filter upwards through the chemical packing in the column. The interferences adhere to the chemical packing in the column and the purified extract passes through a membrane (frit) to the surface of the column. Many of our columns are available in both formats with the same performance parameters. Thus, the costumer can choose between two different formats according to the available equipment in the lab. Only one column is an exception of this rule: The Multisep®211 Fum column used for the clean up of fumonisins works according to the classical SPE principle where 3 steps are necessary for clean up: The columns are rinsed with a solvent to remove remaining interferenc
