Manufacturing Quality Control of N,N-DIMETHYLTHIOFORMAMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies DMF-TA content by retention time and peak area comparison against a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfur Compounds (e.g., dimethyl disulfide) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies volatile sulfur impurities by retention time and mass spectral fragmentation patterns. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions using APHA scale; spectrophotometric version measures absorbance at 430 nm. |
| Density at 20 C | Oscillating U-tube Densitometry | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Refractometry | Measures refractive index using Snell's law via critical angle determination with sodium D-line light source. |
| Non-Volatile Residue | Evaporation and Gravimetry | Quantifies residue left after gentle evaporation of a known sample mass under controlled temperature and vacuum. |
| Odor Impurities | Gas Chromatography-Olfactometry (GC-O) | Detects and characterizes odor-active sulfur volatiles by simultaneous instrumental detection and human sensory evaluation at effluent port. |
