| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 4-methoxy-1-butanol relative to internal/external standard using retention time and peak area. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration based on iodine consumption in pyridine-methanol solvent. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Compares sample color intensity against platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Refractometry | Measures bending of light through sample at specified temperature to determine refractive index. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume under controlled conditions and weighs non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of ground-state atoms in flame/graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration using silver electrode to monitor endpoint potential change. |
| Aldehyde Content | Spectrophotometry after reaction with Purpald reagent | Measures aldehydes via formation of purple chromophore with Purpald, quantified at ~550 nm. |
| Non-Volatile Matter | Gravimetric Analysis | Dries sample at 105 degC to constant weight and determines residue mass as percentage of original sample. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral compounds in solution using sodium D-line source. |
