Micro‐invasive method for studying lead isotopes in paintings

A micro‐invasive technique is presented that enables pigment sampling from individual layers of a painting cross‐section by obtaining a furrow 10–50 μm wide of chosen length. Combined with increased sensitivity of lead (Pb) isotope analysis using multicollector inductively coupled plasma mass spectr...

Summary:A micro‐invasive technique is presented that enables pigment sampling from individual layers of a painting cross‐section by obtaining a furrow 10–50 μm wide of chosen length. Combined with increased sensitivity of lead (Pb) isotope analysis using multicollector inductively coupled plasma mass spectrometry (MC‐ICPMS) equipped with a 1013 Ω resistor or a Pb double‐spike technique, the amount of Pb needed for isotopic analysis is drastically reduced, while maintaining a relative 2 SD precision for 206Pb/204Pb of < 0.02%. The methodology proved able to characterize Pb isotope differences within paint layers.
