Chromalite 15AD1 is a hydrophobic macroporous polydivinylbenzene adsorbent. This polymer is available in 5, 10 and 15 micron, with a very narrow particle size distribution. Chromalite 15AD1 is chemical inert polymer matrix and is fully stablein applications in the range of pH between 1 to 14. Chromalite 15AD1 has a medium porosity (100Å), ideal for separation of medium/small molecules with MW < 1000Da, and can substitute C8/C18 silica with porosity of 50 – 100Å.

Principal Applications

  • Analytical Reverse Phase chromatography (RP-HPLC)
