Glow Discharge Mass Spectrometry (GDMS)

Glow Discharge Mass Spectrometry (GDMS) is an advanced analytical technique used for elemental and isotopic analysis of solid samples. GDMS is particularly valuable for determining trace and ultra-trace elements in materials like metals, semiconductors, ceramics, and geological specimens. The technique involves applying a high voltage to a sample in a low-pressure argon atmosphere, which generates a glow discharge. This discharge ionizes the atoms in the sample, allowing for their identification and quantification using a mass spectrometer. GDMS offers exceptional sensitivity and accuracy, making it crucial in industries such as metallurgy, materials science, and semiconductor manufacturing, where precise elemental analysis is essential for quality control and research.
