Manufacturing Quality Control of ZINC P-TOLUENESULFONATE HYDRATE

Detection Item	Common Analytical Method	Method Overview
Assay (Zn(C7H7SO3)2 content)	Acid-Base Titration after Hydrolysis	Hydrolysis releases sulfonic acid, which is titrated with standardized NaOH using phenolphthalein indicator.
Zinc Content	ICP-OES	Sample is acid-digested and zinc concentration quantified by atomic emission intensity at characteristic wavelength.
Loss on Drying	Gravimetric Analysis	Mass loss measured after drying at 105 C for 2 h under controlled humidity conditions.
Residue on Ignition	Gravimetric Analysis	Non-volatile inorganic residue determined after ashing at 500-600 C.
Chloride Impurity	Ion Chromatography	Chloride ions separated on anion-exchange column and detected conductometrically.
Sulfate Impurity	Barium Sulfate Gravimetry	Precipitation of sulfate as BaSO4 followed by ignition and weighing of residue.
Heavy Metals (Pb, Cd, Hg, As)	ICP-MS	Multi-element quantification after microwave-assisted acid digestion using isotopic dilution or external calibration.
Water Content	Karl Fischer Titration	Electrochemical titration measuring water via reaction with iodine and sulfur dioxide in pyridine-methanol medium.
pH of Aqueous Solution	Potentiometric Measurement	pH measured using calibrated glass electrode in a 1% w/v aqueous suspension.
Particle Size Distribution	Laser Diffraction	Size distribution determined by analyzing angular variation in laser light scattering from dispersed particles.
Organic Volatile Impurities	Gas Chromatography-FID	Residual solvents and organics separated on capillary column and detected by flame ionization.
Microbial Contamination	Membrane Filtration	Viable microorganisms retained on filter membrane, then cultured on appropriate agar media for enumeration.
