对经过液相色谱分离后的化合物进行源内碰撞诱导裂解(CID)，并对化合物及其碎片离子进行精确质量测定，测定质量与理论质量之间误差不超过2。

With in-source collision induced dissociation (CID) and exact mass measurement, the differences between the calculated mass and the theoretical mass of all compounds and fragments were less than 2.

We can be precise about how much bigger by saying, "If the acceleration of a body to a given force is ten times that of a one kilogram mass, then this mass is one-tenth of one kilogram."

我们能精确地知道质量能大多少,只需要说,"如果物体在给定力作用下的加速度,是一个 1 千克物体的加速度的 10 倍,那这个物体的质量就是 1 千克的十分之一"
