OTHER TECHNIQUES
ICP-OES Inductively Coupled Plasma OES
• A variant of AES which uses a very
hot plasma (10 000K) to atomise the analyte.
hot plasma (10 000K) to atomise the analyte.
• Higher sensitivity, multi-element analyses.
ICP-MS Inductively Coupled Plasma Mass
Spectrometry
Spectrometry
• A MS detector
is used rather than the photomultiplier analyser used in AES.
• Still higher sensitivity and harder to use.
XRF X-Ray Fluorescence
• Used for multielement
analysis of solids.
