Nitrite poses health risks. This study evaluates the results of using tannic acid- protected fluorescence copper nanoclusters (TA-CuNCs) to detect nitrite in food.

Our annual review of new products for atomic and molecular spectroscopy, including details by category and highlights of overarching trends.

L. Robert Baker, the 2021 Emerging Leader in Atomic Spectroscopy, applies ultra- fast, time-resolved X-ray spectroscopy to explore charge transfer at surfaces, to understand electron transfer, energy conversion, electrochemistry, and catalysis.

Raman spectroscopy offers promise for the evaluation of breast cell lines and tissue. Rina Tannenbaum of Stony Brook University discusses this work.

Determining the components in a mixture can be a significant challenge in infrared spectroscopy, but spectral subtraction can help. We show the proper way to perform spectral subtraction, and the pitfalls to avoid.

EPA Method 200.8 and the Lead and Copper Rule Revisions don’t allow use of modern ICP-MS technology with a collision cell. Instead, correction equations can be used to compensate for polyatomic interferences.
