No full textAPPLICATIONS OF EVOLVED GAS ANALYSIS - PART 2: EGA BY MASS SPECTROMETRY
No full textThe analytical applications of the evolved gas analysis (EGA) performed by mass spectrometry, for the period extending from 2001 to 2004, are collected in this review. By this technique, the nature of volatile products released by a substance subjected to a controlled temperature program is on-line determined, with the possibility to prove a supposed reaction, either under isothermal or under heating conditions.

Thermoanalytical study of benzimidazole complexes with transition metal ions: Copper(II) complexes
No full textThe benzimidazole molecule (Benz) is known to play a fundamental role in many biological systems; it is moreover, extensively used in industrial processes as a corrosion inhibitor for metal and alloy surfaces.
The synthesis and the thermal profile of some Cu (II) complexes of benzimidazole of general formula CuBenz4X2 are proposed.
A parallel study of these complexes with an ionization mass spectrometer is also reported
Analytical comparison of calorimetric, enzymatic and chemical methods for quantitative determination of cholic acids
No full textSeveral methods for the determination of cholicacids have been examined using pure cholicacid as standard. Some analytical aspects have been checked and evaluated. Two methods based on DSC were considered using the detection and measurement of the heats of oxidation and heats of fusion, respectively. The results were compared with those obtained both by the enzymaticmethod using 3α-hydroxysteroid dehydrogenase as reagent and by a chemicalmethod based on the Pettenkofer reaction. Operative procedures of the last method have been tested and improved with respect to the Irvin procedure in some cases.
The discussion is reported in terms of precision, sensitivity and possible fields of application for the examined method
THERMOGRAVIMETRY STUDY ON THE WATER IN SECRETORY-TISSUES OF RABBIT
No full textIsothermic and dynamic thermogravimetry was applied to rabbit parotid and submandibular glands to quantitate and characterize the water present inside them. Isothermic thermogravimetry demonstrated that at 95-degrees-C a quota of water is still present in the samples. Dynamic thermogravimetry evidenced that temperatures higher than 200-degrees-C are required for the release of the highest energy bound water from both glands. In addition during present research it was found that submandibular gland, an organ considered histologically homogeneous, reveals an heterogeneous distribution of water
CHARACTERIZATION OF MOUSE SALIVARY-GLANDS BY WATER-CONTENT AND TYPE
No full textThe thermoanalytical analysis was applied to samples of sublingual, submandibular and parotid glands from sexually mature mice of both sexes. Findings indicated that the three salivary glands show a behaviour of water release characteristic for each type of gland. Derivative thermogravimetry curves concerned with the sublingual and parotid glands belonging to male and female subjects exhibited overlapped results. As regards submandibular gland, instead, some differences emerged between subjects of different sex. Water content and types in sublingual, submandibular and parotid glands were discussed and related to the different morphological expression, histochemical reactivity and chemical composition of these organ tissues
