Manufacturing Quality Control of ERYTHROSIN B

Detection Item Common Analytical Method Method Overview
Assay (Purity) UV-Vis Spectrophotometry Measures absorbance at lambda-max (~526 nm) and calculates concentration using molar absorptivity and Beer-Lambert law.
Heavy Metals (as Pb) Atomic Absorption Spectroscopy (AAS) Quantifies total heavy metal content after wet digestion by measuring atomic absorption of vaporized metal atoms.
Arsenic ICP-OES Determines arsenic concentration via emission intensity of As I 193.696 nm line after microwave-assisted acid digestion.
Sulfated Ash Gravimetric Analysis Measures residue mass after high-temperature incineration of sample with sulfuric acid to convert organic matter to inorganic sulfate ash.
Chloride Potentiometric Titration with AgNO3 Uses silver nitrate titrant and silver indicator electrode to detect endpoint based on change in potential due to AgCl precipitation.
Water Content Karl Fischer Coulometric Titration Electrochemically generates iodine to react with water; quantifies water from coulombs consumed in the reaction.
pH of 1% Aqueous Solution pH Potentiometry Measures hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode and reference electrode.
Organic Impurities (Related Substances) HPLC-UV Separates and quantifies structurally related compounds using reversed-phase C18 column and UV detection at 254/526 nm.
Residue on Ignition Gravimetric Analysis Weighs non-volatile residue remaining after ignition at 700-750 C in a muffle furnace.
Solvent Residues (e.g., Ethanol, Acetone) GC-FID Separates volatile solvents by gas chromatography and detects them via flame ionization response.
Particle Size Distribution Laser Diffraction Analyzes scattered laser light intensity pattern to calculate size distribution based on Mie scattering theory.
Microbial Limits Membrane Filtration and Plate Count Filters sample through membrane, incubates on appropriate agar media, and enumerates viable aerobic bacteria and fungi colonies.
