EC HPLC column (analytical), NUCLEODUR PolarTec, 3 µm, 125x4.6 mm [18310][MICROLAB] Stability: 2-100 ppb levels stableBased on high purity NUCLEODUR silica gel, a polar group was embedded in a hydrophobic C18 modification. As a result, this HPLC phase shows steric and an increased polar selectivity. This HPLC phase shows a good performance under high aqueous conditions. It is a hydrophobic phase with pronounced hydrophilic properties. Separation mechanism based on hydrophobic (van der Waals) and polar interactions. Suitable for LC MS due to low bleeding
