An ion source is provided comprising a nebuliser or electrospray probe (1) for nebulising a sample and an impact surface or target electrode (5). The impact surface or target electrode (5) comprises a tarnishable or oxidisable metal or an alloy comprising tarnishable or oxidisable metal. Also provided is an ion source comprising a nebuliser or electrospray probe with a central wire comprising a tarnishable or oxidisable metal or an alloy comprising a tarnishable or oxidisable metal or an alloy comprising a tarnishable or oxidisable metal. Adducts with relatively heavy metals result in simplified multiply-charged mass spectra that are easier to interpret.
