Mass Spectral Profile for Rapid Differentiating Beta-Lactams from Their Ring-Opened Impurities

Figure 5

Represent CID spectra of deaminated daughter ion of cefprozil (a) and amoxillin (b). The spectra were obtained with the ion trap. The resonance voltages were both 1 volt, and the activating times were both 20 millisecond. The activating widths were both 10 amu.
