by WATERS
If your method calls for µBondapak packings, there is only one µBondapak packing material. Many companies claim to have columns with µBondapak-like selectivity but not one has ever passed Waters stringent QC batch test. Waters set the standard for reproducible, high-performance chromatographic columns. Waters µBondapak columns are still the most widely referenced and requested columns in the world.
µBondapak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 10 µm particle technology. As a starting point for preparative chromatography, no other column can provide the balance between resolution, throughput and cost.
