HECTOR-W is designed for the separation of biological compounds, such as proteins, peptides, nucleotides, and oligosaccharides. The HECTOR-W pore size affects analysis and provides high efficiency and a good peak shape. It is produced with the use of high-purity silica and is fully end-capped. It is available in 3, 5, and 10 μm particle sizes and in various column sizes. The advanced total end-capping system that is used in its production makes this material excellent for analyzing basic substances and some metal complexes, where any trace of residual silanol sites will cause peak tailing.

The NH2 phase is for reversed- or normal-phase separation. It is excellent for the reversed-phase analysis of sugars, sugar alcohols, and anionic compounds, or for hydrogen-bonding compounds, under normal-phase conditions.
