Manufacturing Quality Control of 4427-97-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and potentiometric or phenolphthalein endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 700-800 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms at element-specific wavelengths. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride anions using an anion-exchange column and conductivity detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color to APHA platinum-cobalt standards or measurement of absorbance at 455 nm in a 10-mm cell. |
| Refractive Index | Refractometry | Determination of refractive index at 20 C using a calibrated Abbe refractometer based on critical angle of total internal reflection. |
| Specific Gravity | Digital Density Meter | Measurement of density relative to water at 20/20 C using oscillating U-tube principle. |
| Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Identification and semi-quantification of low-boiling contaminants via thermal equilibration and mass spectral detection. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation of structurally related compounds on a reversed-phase C18 column and quantification using UV absorbance at 210 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid-to-liquid phase transition occurs, observed visually or automatically. |
