X-ray fluorescence (XRF) spectroscopy has been an important method in the study Stonehenge.

Sapienza Università di Roma team reports near-infrared (NIR) techniques that identify and quantify cocaine and cutting agents through sealed police evidence bags, addressing safety and chain-of-custody concerns in forensic laboratories.

A method transfer case study describing how digestion vessel capability, elevated microwave digestion temperature, and optimized acid chemistry resolved poor palladium spike recovery and memory effects during ICP-MS trace metal analysis, achieving consistent 98–100% recoveries with no observable carryover.

In this preview of the upcoming American Chemical Society (ACS) Fall 2026 Meeting, we sat down with Pavithraa “Pavi” Sundararajan, a postdoctoral fellow at NASA Ames Research Center, talks about her career journey and what inspired her to become an astrochemist.

A forensic case study using FT-IR, portable Raman spectroscopy, and SEM-EDS to differentiate three-layer automotive coatings from a hit-and-run accident, demonstrating that combining complementary spectroscopic and elemental techniques improves the accuracy of paint evidence identification.

The deadline to submit nominations for the 2027 Coblentz Award, presented annually to an outstanding young molecular spectroscopist under the age of 40, has been extended to August 31, 2026.

In this preview of the upcoming American Chemical Society (ACS) Fall 2026 Meeting, we sat down with Pavithraa “Pavi” Sundararajan, a postdoctoral fellow at NASA Ames Research Center, to ask her about what she is looking forward to at the conference.

The Altar Stone cannot be taken to a laboratory for analysis, but portable Raman analyzers are getting the job done on-site.

The 29th International Conference on Raman Spectroscopy (ICORS) takes place next week in Istanbul, Turkey. We preview the conference here.

This interactive e-book covers the recent trends and developments in analytical spectroscopy and how it is being used in archaeology and cultural heritage analysis.

Infrared (IR) spectroscopy, paired with statistical modeling, can non-destructively distinguish human, dog, and cat bloodstains on sand and soil, offering a preliminary proof-of-concept for field-deployable forensic screening tools.

In this preview of the upcoming American Chemical Society (ACS) Fall 2026 Meeting, we sat down with Pavithraa “Pavi” Sundararajan, a postdoctoral fellow at NASA Ames Research Center, discusses how spectroscopic techniques have been applied in the study of nitrogen-containing polycyclic aromatic hydrocarbons (PAHs).

Top articles published this week include a new peer-reviewed article how laser pulse width and repetition rate affect quantitative elemental analysis of aluminum alloys using fiber laser-induced breakdown spectroscopy (LIBS) and more.
