| Chemical Research | Laboratory reagent (for organic synthesis research or as reference standard) | Used in purification and analytical testing |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities by retention time and UV absorbance relative to the main peak. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent residues are equilibrated in headspace vials and quantified via GC-FID using calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation of chloride ions on an anion-exchange column followed by quantitative detection via conductivity. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Element-specific detection after microwave-assisted acid digestion and plasma ionization. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Sample is charred, sulfated with H2SO4, and ignited at 700-800 C; residue mass is measured gravimetrically. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection in Standardized Lighting | Assessment of physical state, color, and presence of visible particulates or phase separation against established visual standards. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral components in solution at specified concentration and path length. |
| Bulk Density | USP <616> Tap Density Method | Mass per unit volume determined after mechanical tapping of a known mass in a graduated cylinder to achieve reproducible packing. |
