Response to Comments on “Application of laser ablation multicollector inductively coupled plasma mass spectrometry for the measurement of calcium and lead isotope ratios in packaging for discriminatory purposes”

“…Application of the methodology with the newly-characterised material as a screening technique, not a stand-alone method, to assess a suite of real packaging materials from different countries, for which there is no "real" standard. [2] Response to (i) We thank Dr Gordon for her detailed analysis and explanation of the expected findings. We acknowledge Dr Gordon's main point that not all potential interferences in the samples, particularly the polyatomic interferences from the presence of other matrix components in the packaging materials, were resolved and that the data presented may not purely be reflecting Ca isotopic data.…”
