Industrial Applications of GALLEIN
| Industry | Application | Process |
|---|---|---|
| Chemical Analysis | pH Indicator | Used in acid-base titrations; color change range: pH 8.2 (colorless) to 10.0 (red), enabling pH determination via visual color transition |
| Laboratory Research | Chemical Reagent | Applied as a colorimetric reagent in laboratories to monitor reaction progress under alkaline conditions |
Manufacturing Quality Control of GALLEIN
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purified Content) | UV-Vis Spectrophotometry | Quantification based on absorbance at characteristic wavelength (e.g., ~590 nm) using molar absorptivity and Beer-Lambert law. |
| Loss on Drying (LOD) | Gravimetric Analysis | Mass loss measured after drying at 105 C for 2 hours under controlled humidity and atmospheric pressure. |
| Water Content (Karl Fischer) | Coulometric Karl Fischer Titration | Electrochemical determination of water via iodine generation and stoichiometric reaction with water in anhydrous methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile inorganic residue after ashing at 700-800 C in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantitative measurement of metal ions (e.g., Pb, Cd, Hg, As) after acid digestion and flame or graphite furnace atomization. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using silver electrode to detect endpoint via potential change from AgCl precipitation. |
| Sulfate Impurity | Turbidimetric Analysis | Formation of barium sulfate precipitate in acidic medium; quantification via light scattering measurement. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separation and quantification of structurally similar impurities using reversed-phase C18 column and UV detection. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity using calibrated glass electrode in saturated aqueous suspension (1% w/v). |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating rate. |
| Solubility in Ethanol | Visual Dissolution Test | Qualitative assessment of complete dissolution in specified volume of ethanol at 25 C within defined time. |
| Particle Size Distribution | Laser Diffraction Analysis | Size distribution derived from angular scattering pattern of laser beam passing through dispersed sample in liquid medium. |
