YMC-Triart C18 ExRS 層析管柱
YMC-Triart C18 ExRS採用有機雜化矽膠(hybrid silica-based)之高覆蓋率(high-coverage)C18液相層析管柱。 由於高碳載量(high carbon loading)，YMC-Triart C18 ExRS的疏水性(hydrophobicity)很高，這使得YMC-Triart C18 ExRS適合與疏水性異構體(hydrophobic isomers)和結構類似物(structural analogs)使用。 有鑑於YMC-Triart C18 ExRS具有出色的化學和物理耐久性，可提供HPLC工作者在選擇分離條件時更大的靈活性，有利於進行分離方法開發和例行分析檢驗時使用。
