Unibeads from GL Sciences are adsorbents for gas chromatography. The Unibeads series consists of spherical silica with different characterisations and pore sizes. The Unibeads series also includes Unipak S. This is also a spherical silica, which is useful for analysing ethane, ethylene, acetylene and higher carbons.
