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.

BISCHOFF, Analysentechnik und -geräte GmbH (internationally known as BISCHOFF Chromatography) was founded in 1980 by Klaus Bischoff as a Service Company doing Refill of used HPLC-Columns. The daily work of K. Bischoff at a well known HPLC-Manufacturer in the fields of Development, Applications, Quality Control, Sales and the intensive relations to well known Professors on foreign and national Universities influences since 1980 the company philosophy. It is our aim to deliver user- and applicationfriendly products of high quality and lifetime which are manufactured with modern technology to reduce costs and lead to reliable solutions. In addition we feel responsible as innovative High-Tech-Company to save resources, improve environmental protection and to dramatically decrease environmental pollution by optimizing separation processes with miniaturisation of instruments at the same time. Due to that reasons the worldwide unique offer for Refill of HPLC-Columns was quickly accepted by customers.
