The advent of superficially porous particles (SPPs) for packed HPLC columns has changed the way that many practitioners have approached the problem of developing needed separations. The very high efficiency of such columns, combined with convenient o

We present the long-term retention and separation data reproducibility between 2013 and 2020 for analytical scale (4.6 mm internal diameter) superficially porous particle (SPP) columns. The retention factor for a small molecule—naphthalene—separa

Types of particles have been fundamental to LC separation technology for many years. Originally, LC columns were packed with large-diameter (>100 μm) calcium carbonate, silica gel, or alumina particles that prohibited fast mobile-phase speeds becaus

To facilitate mass transport and column efficiency, solutes must have free access to particle pores to facilitate interactions with the stationary phase. To ensure this feature, particles should be used for HPLC separations which have pores sufficien

The Tanaka test is a classical characterization scheme designed in 1989 for highlighting the main reversed phase attributes of C18 columns: hydrophobicity, shape/steric selectivity, hydrogen bonding, ion exchange (pH 7 environments). In this short co

Superficially porous particles (SPP) in the 2.5 - 2.7 μm range provide almost the same efficiency and resolution of sub-2 μm totally porous particles (TPP), but at one-half to one-third of the operating pressure. The advantage of SPP has led to the

Superficially porous particles (also called Fused-Core, core shell or porous shell particles) show distinct advantages over comparable totally porous particles for separating small molecules. Columns of Fused-Core particles exhibit very high efficien

The separation range of superficially porous particles (Fused-core®) has been extended by design of particles with 160 Å pores. These particles show superior kinetics (lower resistance to mass transfer), allowing fast separations of peptides and sm

Fused-core superficially porous particles have recently created considerable interest for high-performance liquid chromatography separations because of their unusual high column efficiency and much lower back pressure when compared to sub-2-microm pa
