Manufacturing Quality Control of 1,3-BENZENEDIMETHANETHIOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine consumption in pyridine-methanol solvent. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison against Platinum-Cobalt Scale | Compares sample color to standardized Pt-Co solutions under controlled lighting and path length. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Abbe Refractometer | Measures bending of light at air-sample interface to calculate refractive index at specified temperature. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known sample mass at 105 C, cools in desiccator, and weighs non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies metal content after wet digestion and atomization by measuring absorption of element-specific wavelength. |
| Sulfur Content | Combustion UV Fluorescence | Oxidizes sample to SO2, then detects SO2 concentration via UV-induced fluorescence intensity. |
| Odor Profile | Gas Chromatography-Olfactometry (GC-O) | Separates volatile components and assesses odor character/intensity via human panel detection at effluent port. |
| Non-Volatile Matter | Gravimetric Analysis | Filters sample through pre-weighed membrane, dries residue at 105 C, and determines mass gain. |
| Trace Aldehydes | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies aldehyde derivatives (e.g., DNPH adducts) using reverse-phase column and UV absorbance. |
