Supplementary Information: Optimized ICP-MS Analysis of Elemental Impurities in Semiconductor-Grade Hydrochloric Acid

Top articles published this week include a tribute to John Albert Reffner, who was known for his work in infrared microspectroscopy, an application of Raman spectroscopy to improve recycling practices, and an Icons of Spectroscopy column on Karl Norris, known as the founder of near-infrared (NIR) spectroscopy.

A new study published in Spectrochimica Acta Part A by Dominik Heger and colleagues at Masaryk University reveals that phenol's photophysical properties change significantly when frozen, potentially enabling its breakdown by sunlight in icy environments.

This note details a microwave digestion method for Li-ion cathode samples, enabling accurate elemental analysis through ICP-OES with minimal sample loss.

The Trump administration's proposed tariffs on multiple industries could profoundly impact analytical chemists working in industry, government, and academia.
