Laser ablation laser ionization time-of-flight mass spectrometry (LALI-TOF-MS) can quantify elemental constituents without the need for matrix-matching, making it attractive for metals testing, particularly for additive manufacturing.

Epoxies are perhaps the most economically important functional group of polymers. We explain how to interpret their spectra.

What can spectroscopic techniques, such as portable X-ray fluorescence spectrometry (PXRF), reveal about the sarsen megaliths of Stonehenge and where they originated?

High-performance instrumentation requires many critical components. We focus here on energy sources, lasers, and detectors.

Spectroscopists offer their views on the their salaries and working conditions, including how they are faring through the social and economic challenges still gripping the world.

The “fingerprint in the fingerprint” region is key for active pharmaceutical ingredient (API) identity testing. We explain why.
