The ReproSil C18 AQ column has established itself as a standard for catecholamines
separation, one among many other applications which has been solved by this column.
The C18 AQ and many other ReproSil columns and packing materials are developed by

Dr. Albin Maisch in Germany. His columns have extraordinary resolution and peak symmetri.
Most popular particle size is 5 or 3 µm but the Gold Columns with 1.5 µm material
is slowly growing in popularity due to the increased use of LC/MS.
The 3 µm ReproSil packing materials are very much asked for by many CE and microLC users.
They each buy one gram powder to produce their own capillary columns.
Apart from the silica based columns, Dr Maisch has a line of polymeric columns for
separation of organic acids, carbohydrates etc.
These ReproGel columns, normally 250 x 8 mm in size, are as the rest of Maisch´s
column program very priceworthy and give superb resolution.
