ReproSil Gold 100 XBD from Dr. Maisch HPLC GmbH is a high-performance range of high-purity silica HPLC columns with a 100 Å pore size and eXtra Base Deactivation (XBD) for optimal performance with basic analytes. The advanced surface treatment effectively suppresses silanol activity, ensuring excellent peak symmetry, sharp peaks, and high reproducibility in both isocratic and gradient methods.
Available in C18 and C8 bonded phases, the ReproSil Gold 100 XBD series provides strong or balanced hydrophobic retention, making it suitable for a wide variety of small-molecule applications in pharmaceutical, environmental, and food analysis.
ReproSil Gold 100 XBD columns from Dr. Maisch HPLC GmbH combine base deactivation technology with premium silica purity – the preferred choice for high-performance small-molecule HPLC separations.
