Our custom nano pre-column usually has length of 1 - 5 cm with 360 µm OD and different inner diameters with one end fritted. The chemistry of our pre-made column is C18 or C8, but you may send your own packing materials for custom packing.

Please specify the packing material, column ID., length, and any other information when ordering. It is crucial that you use compatible packing material for pre- and analytical columns in order to obtain optimal retention of your analytes and peak shape. Please feel free to contact us if you have any questions regarding how to choose the right packing materials.

Free pre-columns are available if a customer pays a small shipping and handling cost. Please contact us for your specific needs.
