Mitiglinide calcium was quantitated by multiple reaction monitoring (MRM) mode with negative electrospray ionization (ESI -).

采用电喷雾负离子化，多反应监测(MRM)进行定量分析。

So we are really looking at this reaction here H+ for ionization. It is H gas neutral goes to H plus in the gas phase plus the electron. And, furthermore, we can have multiple ionization energies.

所以我们真正看到的是,电离，它是在气相中H变为,和电子的过程，还有，我们能电离能加倍。
