Matrix-matched standards are crucial for XRF accuracy. Dr. Shiv Verma outlines their impact on elemental analysis and the prevention of calibration errors.

The role of gas chromatography (GC) in forensic analysis is spotlighted. Gas chromatography (GC) techniques are increasingly central to forensic chemical analysis.

Titan’s harsh chemistry breaks basic rules, offering new clues about how life’s building blocks might form in space.

Scientists have found that on Titan, substances that should remain separate can actually combine under freezing conditions.
