On the two-phase sample transport of carbon in LA-ICP-MS and its practical implications for trace metal analysis in polymer matrices: classification and sensitivity

The findings of this work are highly significant when analyzing carbon-based samples as we demonstrate a relationship between the analyte's sensitivity and the ratio of gaseous carbon species formed. Additionally, the proof-of-concept for LA-ICP-MS based polymer classification enables easier selection and application of matrix-matched standards for quantitative analysis in polymers.
