• 提示：详情请下载说明书。

• 介绍：

  1、此产品为25mg/瓶，即37种脂肪酸总重为25mg，样品量少不好取，有时候会积累在瓶冒上，开瓶前将瓶子低速离心或使劲甩 一甩，使样品进入瓶底部再开瓶

  2、国标上用正己烷或者正庚烷溶解，但我们建议选择氯仿或甲醇溶剂将产品溶出，因为正己烷或更低极性溶剂极性低，比较难溶出样品。

  3、直接在瓶子里溶解，溶剂注入瓶子后尽量多震荡，使样品溶解完全，取出溶 液后再重复用溶剂洗瓶两遍，合拼溶液，然后定容。

  4、每种脂肪酸成分表参见说明书，具体气相方法参见说明书。

  注意事项：

  色谱柱尽量选择100m的规格，如果是30m的请自行摸索降低升温速率来达到所有峰都分离开。
