Manufacturing Quality Control of 1738-36-9
| 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 mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected by current change. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and potentiometric or phenolphthalein endpoint detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color intensity against platinum-cobalt standard solutions or absorbance measurement at specified wavelength. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 C | Digital Refractometer | Determination of refractive index by measuring critical angle of total internal reflection of light passing through the sample. |
| Residue on Evaporation | Gravimetric Analysis (Weight Loss on Drying) | Evaporation of a known mass of sample under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separation of chloride anions on an anion-exchange column and quantification via conductivity response relative to calibration standards. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Quantification of total heavy metals following microwave-assisted nitric acid digestion and flame or graphite furnace AAS measurement. |
| Aldehyde Impurities (e.g., Acetaldehyde) | Gas Chromatography with Headspace Sampling and FID | Headspace GC analysis to volatilize and separate low-boiling aldehydes, detected and quantified by flame ionization. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporation of specified volume under nitrogen stream at 105 C, followed by cooling and precise weighing of residue. |
| Odor | Sensory Evaluation (Trained Panel) | Organoleptic assessment by qualified personnel to detect off-odor deviations from reference material under standardized conditions. |
