Differential thermal analysis instrument design

In this work, thermal analysis methods are introduced and differential thermal analysis (DTA) is briefly investigated, designed and constructed. The instrument then checked with native sulphates which are CaSO^.^O, MgSO^.TE^O, MgSC^.I^O, CuSO^.Sf^O, FeSO^.Tl^O, NiSO^.TI^O and ZnSO^O. Analysis have been carried out to the temperature range of (room temperature - 350 C) and the exponential heating rate is used. The obtained DTA curves are compared with literature. As seen that, the resultant curves which are obtained as same as the available documents. The minimum detectable sample is found as 20 mg.Keywords: Thermal analysis, DTA,
