Differential Thermal Analysis of Phospholipids
Nature, 1965FOR many years the melting points of both synthetic and natural phospholipids have been measured and recorded1–3. An examination of a given class of phospholipids reveals that these melting points are, to a large extent, independent of the fatty acid residues present.

The Differential Thermal Analysis of Quartz
American Industrial Hygiene Association Journal, 1961Abstract The differential thermal method for the analysis of quartz is discussed and the literature briefly reviewed. The design and construction of a D.T.A. apparatus is described, and details of some of the results obtained with the present apparatus are given.

Differential thermal analysis (DTA) is a thermo-analytical technique which is used for thermal analysis where thermal changes can be studied. It is used to determine the oxidation process, decomposition, and loss of water or solvent. In this chapter we have discussed the basic principle of DTA along with its instrumentation, working, factors affecting ...

The automation of thermal analysis instrumentation: differential thermal analysis
Analytica Chimica Acta, 1970Abstract An automated DTA instrument is described which is capable of studying eight individual samples, each contained in a glass capillary tube, in a sequential manner. The samples are automatically introduced into the furnace, pyrolyzed to a preselected temperature limit, and then removed. After the furnace has been cooled back to room temperature,

Characterization and analysis of waxes by differential thermal analysis
Talanta, 1967The characterization of waxes by differential thermal analysis is described. An endothermic peak at 475-480 degrees is characteristic of microcrystalline and polyethylene waxes, and measurement of its area provides a method for the estimation of these waxes in mixtures.

Purity determinations by differential thermal analysis
Talanta, 1967Measurement of the melting-point depression of impure samples was compared with a differential method that involved running the impure sample against a pure sample of the same material. Samples of highly purified benzophenone to which had been added known quantities of 4-methylbenzophenone were studied.

Differential thermal analysis (DTA) is an instrumental technique used for studying the physical and chemical changes that occur in materials as they are heated or cooled. When a material undergoes a physical change, such as melting or crystalline transformation, or when a chemical reaction occurs, energy is either absorbed or given up.
