Product Detail
Company Profile

Utilizing proprietary surface technologies, SRT SEC phases are made of the uniform, hydrophilic, and neutral nanometer thick films chemically bonded on the high purity and enhanced mechanical stability silica. This proprietary surface technology results in excellent column-to-column reproducibility. The nature of the chemical bonding and the maximum bonding density of the thin film benefit SRT SEC phases with high stability and negligible non-specific interactions. Along with the widest pore size selection of 100, 150, 300, 500, 1000 and 2000Å, SRT SEC packings have highest capacity that enables highest resolution.
