Method for mass spectrometry |
| 摘要 |
A method is provided for mass spectrometry. The method includes generating precursor ions from a sample; transmitting the precursor ions into a collision cell; generating product ions in the collision cell; detecting the precursor and product ions; applying modulation to one or more of the precursor ion intensity and the product ion intensity; and identifying precursor ion and product ion relationships by analyzing intensity profiles defined by the modulation. |

1. A method of mass spectrometry, the method comprising:
generating precursor ions from a sample; transmitting the precursor ions into a collision cell; generating product ions in the collision cell; detecting the precursor and product ions; applying modulation to vary the number of precursor ions, wherein the modulation applied comprises varying a parameter upstream of the collision cell such that the precursor ion intensity varies in a compound dependent manner; and identifying precursor ion and product ion relationships by analyzing intensity profiles defined by the modulation. |
