Manufacturing Quality Control of 5157-75-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component peak area relative to calibrated standard using flame ionization detection. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions by titration with silver nitrate using a silver indicator electrode. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemically quantifies water via iodine generation proportional to sample water content. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously detects trace metal concentrations by measuring element-specific atomic emission intensities. |
| Iron Content | Atomic Absorption Spectroscopy (AAS) | Quantifies iron by measuring absorption of light at characteristic wavelength by ground-state Fe atoms in flame. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness intensity by matching sample color to APHA platinum-cobalt standard scale. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Abbe Refractometer | Measures ratio of light velocity in air vs. sample based on critical angle of total internal reflection. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Identifies and quantifies low-boiling contaminants by GC analysis of equilibrated vapor phase above sample. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a defined aqueous dilution using calibrated glass electrode system. |
