一般說明

Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column. SP®-2340 is a cyanopropylsiloxane stationary phase, and has high polarity and temperature resistance.
应用：该非键合色谱柱具有同类中最高的极性。与所有通用双氰丙基丙基色谱柱一样，它可在高温和低温下非常有效的分离脂肪酸甲酯（FAME）、二恶英、碳水化合物和芳族化合物的几何异构体。
USP 代码 ：该柱符合 USP G5 要求。
相：
  • 非键合
  • 聚（双氰丙基硅氧烷）
温度限制：
  • 常温至 250°C（等温或程序升温）

應用

Capillary column coated with SP®-2340 stationary phase may be used in gas chromatographic analysis and separation of cis/trans isomeric fatty acids.
