FAQ
Is Hybrid Particle Technology Better Than Silica-Based Stationary Phases? Silica has long been used as a stationary phase because of its positive attributes, including high efficiency and mechanical strength. However, it also is known for poor peak shape for bases and a limited pH range. The common alternative has been polymer-based stationary phases, however, they have poor efficiency and unpredictable peak elution.
Hybrid Particle Technology is able to combine the best attributes of both these materials while overcoming their respective challenges. Hybrid Particle Technology has high mechanical strength, high efficiency, excellent peak shape for bases, and easy scale-up from analytical to preparative chromatography.
