The 80/100 is refering to the mesh size range of the actual Porapak Q particles. The larger the mesh number the smaller the diameter of the bead. In this case 100 refers to a diameter of 149 microns and 80 refers to a diameter of 177 microns. Therefore, the particles in this product will range between 149 and 177 microns.
