| 摘要 |
A device and a method for identifying metalloproteins are disclosed. The device includes a first separation device for separating sample molecules according to their retention times, a first ionization device for ionizing the separated molecules into molecular ions, a second separation device for separating the molecular ions by their size-to-charge ratio, a second ionization device for atomizing the molecular ions and creating atomic ions of interest, and a mass spectrometer for separating and identifying both the molecular ions and the atomic ions by their mass-to-charge ratios. A method includes separating sample molecules according to their retention time, ionizing the separated molecules to form molecular ions, separating the molecular ions according to their size-to-charge ratio, atomizing and ionizing a portion of the molecular ions and identifying the atomic and molecular ions by their mass-to-charge ratio.
