Charge state (z)
The number of protons carried by an ion. Observed m/z = (M + z × 1.007276)/z. Two adjacent charge states determine z without assumption.

- Recovering a neutral mass from a set of observed m/z values across charge states. Self-checking: two charge states give two independent estimates.
- Charge-state envelope
- The distribution of intensities across charge states. Its shape carries conformational information: compact molecules ionise at lower charge.
