Manufacturing Quality Control of Carboxyethylgermanium sesquioxide

Detection Item Common Analytical Method Method Overview
Assay (C8H12GeO5) Acid-Base Titration Quantifies carboxylic acid groups via standardized NaOH titration with phenolphthalein endpoint.
Heavy Metal Impurities (Pb, Cd, Hg, As) ICP-OES Simultaneously measures trace metal concentrations by plasma excitation and optical emission detection.
Residue on Ignition Gravimetric Analysis Determines inorganic ash content by high-temperature ignition and weight difference measurement.
Loss on Drying Thermogravimetric Analysis Measures volatile content by mass loss after controlled heating under specified conditions.
Chloride Content Potentiometric Titration Quantifies chloride ions using silver nitrate titrant and silver indicator electrode.
Sulfate Content Gravimetric Analysis Precipitates sulfate as BaSO4 and determines concentration from dried precipitate mass.
Iron (Fe) Impurity AAS Measures iron concentration by atomic absorption of characteristic wavelength light in flame atomizer.
Water Content Karl Fischer Titration Determines water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol medium.
pH of Aqueous Solution Potentiometric pH Measurement Measures hydrogen ion activity using calibrated glass electrode and reference electrode.
Organic Volatile Impurities GC-FID Separates and quantifies residual solvents by gas chromatography with flame ionization detection.
Particle Size Distribution Laser Diffraction Analyzes size distribution by measuring angular variation in laser light scattering pattern.
Bulk Density Volumetric Method Calculates mass per unit volume using standardized cylinder and tapping procedure.
