A methodological problem in thermoanalytic studies arising from admixed fluoride in the samples.
At a temperature just above the collagen denaturation point the aluminium walls of the pans used in microcalorimetric measurements react exothermically with NaF in test solutions. This formation of the fluor-aluminium complex cryolite is assumed to be catalyzed by the denaturing collagen.
