Manufacturing Quality Control of Cycloheptanol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative separation and detection of cycloheptanol and impurities based on volatility and retention time. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine to determine trace water content via stoichiometric reaction. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color against platinum-cobalt standard solutions or measurement at 430 nm. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using calibrated prism-based instrument. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of fixed sample volume to dryness followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion by measuring absorbance of ground-state atoms at characteristic wavelengths. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporation of known sample mass to constant weight and calculation of residue percentage. |
| Aldehyde Content | Spectrophotometric Determination (with DNPH) | Derivatization of aldehydes to hydrazones followed by UV-Vis absorbance measurement at ~360 nm. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride anions using ion-exchange column and conductivity detection. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Thermal equilibration of sample in sealed vial followed by GC analysis of volatile organic residues. |
