Manufacturing Quality Control of 13360-92-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Acid Value | Acid-base titration with KOH ethanol solution | Neutralization of acidic impurities by standardized potassium hydroxide solution in ethanol, measured by endpoint detection. |
| Color (APHA) | Visual comparison or spectrophotometric measurement | Comparison of sample color intensity to APHA platinum-cobalt standards using transmitted light at 430 nm. |
| Moisture Content | Karl Fischer titration | Electrochemical titration where iodine reacts stoichiometrically with water in the sample using pyridine/methanol reagent. |
| Residue on Ignition | Gravimetric analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing and cooling to constant weight. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of trace metals via atomic emission spectroscopy following acid digestion and plasma excitation. |
| Chloride Content | Ion chromatography | Separation and conductivity-based quantification of chloride ions in aqueous extract using anion-exchange column. |
| Phosphorus Content | UV-Vis spectrophotometry after ammonium molybdate reaction | Formation of phosphomolybdenum blue complex measured at ~820 nm for total phosphorus determination. |
| Refractive Index | Refractometry | Measurement of light bending angle through liquid sample at specified temperature to assess purity and composition. |
| Specific Gravity | Pycnometry | Density determination by comparing mass of known volume of sample to mass of same volume of water at 25 C. |
| Melting Point | Capillary melting point apparatus | Thermal transition observation during controlled heating to identify solid-to-liquid phase change range. |
| Volatile Impurities | Gas Chromatography (GC-FID) | Separation and flame ionization detection of low-boiling organic impurities using capillary column and temperature program. |
