Manufacturing Quality Control of Acetylenedicarboxylic acid monopotassium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies the main component by titration with standardized NaOH solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by ignition at 500-600 C and weighing residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of atomic vapor at characteristic wavelength. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled acidic conditions and determines mass gravimetrically. |
| Iron (Fe) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures Fe concentration by detecting element-specific emission lines after plasma atomization/excitation. |
| pH of Aqueous Solution | Potentiometric Measurement | Determines hydrogen ion activity using calibrated pH electrode in a 1% w/v aqueous solution. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents using capillary column and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in laser light scattering pattern. |
| Bulk Density | Volumetric Method | Calculates mass per unit volume by measuring weight of material freely poured into a calibrated cylinder. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to agar medium, and colony enumeration after incubation. |
