General description

LiChrosolv® 溶剂具有较高的紫外线透射率、低颗粒数、低酸碱度和低蒸发残留量,因而其是可重现分离的理想选择。由于分析型HPLC分离通常在梯度条件下进行,因此我们提供适用的“梯度级”和“等度级”溶剂。这使得所使用的溶剂的梯度影响最小化。

Application

乙腈可用作以下反应的溶剂:
  • 反相高效液相色谱(RP-HPLC)法中的流动性
  • 在等度模式的反相HPLC中用于测定含辣椒和咖喱食品中的苏丹染料。

Features and Benefits

  • 已通过0.2 µm滤膜过滤
  • 高分离度、灵敏度和优化的色谱峰基线分离
