Thermochromatography for evolved gas analysis of apatite materials

AbstractEvolved gas analyses of model inorganic compounds and apatites are described. The measurements were performed on a system comprising a `thermochromatograph', with a low-volume thermal furnace, interfaced to a capillary gas chromatograph via a computer-controlled, pneumatic sample inlet device in the temperature region 70–600°C. The performance of this inherently simpler system is comparable to that of thermogravimetry but is superior in resolving possible reactions when similar materials are analysed.

Impact of anionic substitutions on apatite structure and properties

AbstractA review of the results of the authors on single and coupled substitutions of F for OH, and of CO3 and SO4 for PO4 in synthetic and natural apatites, their influence on apatite structure and properties, studied by peak fitting FTIR, XRD, TG/DTA and TG/EGA methods, is presented. Calcination of carbonate and sulphate substituted apatites leads to the formation of stable stoichiometric apatite.

Evolved gas analysis of apatite materials using thermochromatography

AbstractEvolved gas analyses of model inorganic compounds and apatites are described. The measurements are performed on the system – a `thermochromatograph' (ThGC) – with a low-volume, thermal furnace, interfaced to a capillary gas chromatograph (GC) via a computer-controlled, pneumatic sample inlet device in the 70–600°C region. The `information content' performance of this inherently simpler system is comparable to that of TG/GC/MS and TG/GC/IR systems when similar materials are analyzed.
