Manufacturing Quality Control of 18281-05-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies peanut acid ethyl ester peak area relative to internal/external standard using calibrated response factors. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Measures free fatty acids by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Ester Value | Acid-Base Titration after saponification | Determines total ester content by saponifying sample with excess KOH, then back-titrating unreacted alkali. |
| Iodine Value | Wijs Method (Titration with iodine monochloride) | Measures unsaturation via addition of known excess Wijs reagent to double bonds, followed by iodometric titration of unreacted iodine. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically quantifies water based on stoichiometric reaction of iodine with water in anhydrous methanol-pyridine medium. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Compares sample color to APHA platinum-cobalt standard solutions or measures absorbance at 455 nm in 10 mm cell. |
| Refractive Index | Refractometry at 20 C | Measures bending of light through liquid sample using calibrated refractometer to determine purity and composition. |
| Density | Oscillating U-tube Density Meter | Determines mass per unit volume from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Residue on Evaporation | Gravimetric Analysis (Weight Loss on Drying) | Weighs sample before and after controlled evaporation to quantify non-volatile impurities. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantifies lead and other heavy metals by atomization of digested sample and measurement of characteristic absorption wavelength. |
| Residual Ethanol | Gas Chromatography (GC) with FID detection | Separates and quantifies residual ethanol using headspace or direct injection GC with ethanol-specific calibration. |
| Peroxide Value | Iodometric Titration | Measures hydroperoxides by reaction with potassium iodide under acidic conditions, followed by titration of liberated iodine with sodium thiosulfate. |
