Sampling ambient ionization

Schematic of extraction-based ambient ionization

Extraction-based ambient ionization including (non-spray) liquid extraction (e.g. LESA) and mechanical extraction (e.g. PESI).

Table of sampling-based ambient ionization techniques

Ambient ionization techniques that use non-laser ambient sampling with electrospray or other post-ionization.
