Abstract:
Synthethic glucocorticosteroids (fludrocortisone acetate, fluocinolone acetate, flumethasone pivalate, triamcinolone acetonide and dexamethasone acetate) were determined on the basis of their fluoride content, when deflagrated after Schöniger, in three ways: by potentiometric titration or by direct potential measurement of ion-selective fluoride electrode or by spectrophotometry with lanthanum alizarin complexan.

01:19Precipitation Titration: Endpoint Detection Methods
In argentometric precipitation titrations, endpoints can be detected visually by the Mohr, Volhard, and Fajans methods. In the Mohr method, adding a soluble chromate indicator gives an initial yellow color to the analyte solution. As the titrant is added, the first excess of silver ions forms a red silver chromate precipitate, marking the endpoint. The solution pH should be maintained at about 8 by adding solid CaCO3.

01:19Gas Chromatography: Types of Detectors-II
In gas chromatography, different detectors are employed to meet specific analytical needs. These detectors are often categorized based on their detection mechanisms and the types of compounds they are best suited to analyze. Thermal Conductivity Detectors (TCD), Flame Ionization Detectors (FID), and Electron Capture Detectors (ECD) represent common categories, each with unique operating principles and applications. However, beyond these, several other detectors are designed for more specialized...
