Abstract

Correction for ‘Metal salt assisted electrospray ionization mass spectrometry for the soft ionization of GAP polymers in negative ion mode’ by Theoneste Muyizere et al., Analyst, 2020, 145, 34–45.

The authors regret that the caption and note for Table 2 were incorrect in the original article. The correct version of Table 2 is shown below.
Table 2 Comparison of the observed peaks in the systems with various chloride salts and related parameters in negative ion mode
Chloride NaNO3 or not Series Composition Observed peaks M n M w PDI
“N-with” means “negative ion mode and with chloride salt”.
