PORESPHERE® Chroma: Precisely tailored for chromatography and analytics.
Clearly defined pores
Uniform particles
Especially for column and thin layer chromatography
This silica gel in powder form serves as a standard adsorbent for analytical and preparative chromatography. It enables clean and reproducible results.
Homogeneous flow within the column and a uniform bed
Free from contaminants
Ensures identical interactions between the sample and the adsorbent
Reliable separation with 30, 60, and 100 Å options.
Precision down to the smallest detail
Silica gel powder is the backbone of precise separation processes in chromatography. Manufactured with the highest level of purity and defined pore structures, it offers the perfect balance between surface area and pore volume.
Its reproducible surface chemistry, featuring uniformly distributed silanol groups, ensures that every separation remains consistent and comparable. Combined with a narrow particle size distribution, it guarantees uniform flow within columns and sharp resolution in thin-layer chromatography. These properties make silica gel the standard material in research and industry—wherever clean separations, reproducible results, and maximum precision are essential. Whether in analytical laboratories or preparative chemistry, Silica Gel 60 delivers reliable performance.
Applications.
Thin-Layer Chromatography (TLC)
– Separation technique, analytical chemistry
In thin-layer chromatography, Silica Gel 60 ensures precise separation—even with complex samples. Its fine particle size and uniform pore structure produce sharp, clearly defined spots, while its reproducible surface chemistry guarantees a consistent migration rate.
This makes analyses reproducible and results comparable—an essential requirement for both research and routine analytical work.
Column Chromatography
– Separation technique, analytical chemistry
In column chromatography, Silica Gel 60 ensures a uniform flow of the mobile phase and maximum separation resolution. Its homogeneous particle size distribution prevents the formation of channels or turbulence, allowing each component to be cleanly separated from the next.
The defined pore size and active surface area ensure optimal adsorption and selective elution of molecules—delivering reproducible results that chemists worldwide rely on.
Analytics
– Research
In analytical chemistry, precision is critical. Silica Gel 60 provides this through its high-purity composition and consistent surface chemistry. Molecules interact reliably with the stationary phase, ensuring that measurement results remain reproducible and comparable.
Whether in research, quality control, or preparative applications, Silica Gel 60 sets the standard for clean separations and reliable analyses.
