Exsil Avanti

High-Performance UHPLC/HPLC Silica for Fast, Efficient Separations

Exsil Avanti is a premium high-efficiency silica stationary phase engineered for modern UHPLC and HPLC applications that require fast, precise, and reproducible separations. With a highly controlled pore structure and uniform spherical morphology, Exsil Avanti delivers exceptional chromatographic performance across a broad range of reversed-phase and normal-phase workflows.

Designed for rapid method development and robust routine analysis, Exsil Avanti supports analysts in pharmaceutical, biochemical, environmental, and industrial labs with superior peak shape, high efficiency, and reproducibility — even under demanding gradient and high-pressure conditions. The versatile phase chemistry makes it suitable for a wide spectrum of analytes, ranging from small organic compounds and drugs to moderately sized peptides and polar molecules.

Manufactured with state-of-the-art quality control, Exsil Avanti silica offers excellent mechanical strength, stable surface chemistry, and compatibility with modern HPLC systems. The optimized surface reduces unwanted secondary interactions, resulting in sharp, symmetrical peaks and enhanced resolution.

Exsil Avanti combines high-performance silica technology with versatility and robustness — the reliable choice for analysts seeking fast, efficient, and reproducible results in both modern UHPLC and conventional HPLC applications.
