| Research & Development | Analytical reagent | Used as a reference standard or reaction reagent in laboratory research |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies total acid content by neutralizing with standardized NaOH solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Determines water via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, Fe) by plasma excitation and elemental emission spectroscopy. |
| Chloride | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Iron | Atomic Absorption Spectroscopy (AAS) | Measures iron concentration by atomic absorption of specific wavelength light in flame or graphite furnace. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates against standard white background under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Organic Impurities | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic impurities using capillary column and flame ionization detection. |
| Related Substances | High-Performance Liquid Chromatography (HPLC-UV) | Identifies and quantifies structurally related compounds using reversed-phase column and UV detection. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode. |
