Deconvolution

Seen on mass-spectrometric identity assessments.

Definition

The calculation that recovers a single molecular mass from a series of charge states. A consistent series (every state pointing at the same underlying mass) is what makes an assignment credible rather than a coincidence.

Related terms

Charge state
The number of charges an ion carries, written as [M+nH]ⁿ⁺ for a peptide that has picked up n protons.
Observed mass
The molecular mass recovered from a sample spectrum, reported alongside the theoretical mass and the difference between them.

About mass spectrometry

Terms a reader meets on mass-spectrometric reports from other laboratories, and on confirmatory work sent out. This laboratory has no in-house mass spectrometer, and its certificates carry no mass spectrum.
