Journal Highlight: Development of exact matrix-matching ICP-OES spectroscopy for the analysis of Cu and K in infant formula

Date: Sep 20, 2016

Author: spectroscopyNOW

An ICP-OES method was developed as a low-cost alternative to isotope dilution ICP-MS for measuring K and Cu in infant formula, using an exact matrix-matching approach to minimize biases due to matrix mismatch.

Butts are no joke: FAAS, the evidence

Date: Jul 15, 2016

Author: David Bradley

Graphite furnace atomic absorption spectrophotometry (FAAS) reveals that toxic metals from cigarette butts could be an important source of pollution thanks to the millions that are discarded by smokers and end up on shorelines and in the oceans.
