✦ Synopsis


A survey of microanalytical measurements on interplanetary dust particles (IDPs) and interstellar dust grains from primitive meteorites is presented. Ion microprobe mass spectrometry with its capability to determine isotopic compositions of many elements on a #m spatial scale has played a special role. Examples are measurements of H, N, and O isotopes and refrectory trace elements in IDPs, and C, N, Mg, and Si isotopes in interstellar silicon carbide grains, and C and N isotopes as well as H, N, A1 and Si concentrations in interstellar graphite grains. Possible future instrumental developments are also outlined.

Thermal analysis-mass spectrometry (TA-m.s.) has been used to study the reactions of coals and coal minerals under combustion-related conditions. The TA-m.s. profiles of the coals give information on combustion performance (ignition, peak combustion and burnout temperatures), and on chemical changes
