Manufacturing Quality Control of 5-Bromo-m-xylene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and carrier gas. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Volatile impurities are vaporized in sealed vials, injected into GC, and quantified by external calibration with standard solutions. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration (NaOH in methanol) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection via changes in eluent conductivity. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Sample is evaporated to dryness under controlled temperature and vacuum; residue mass is measured after cooling in desiccator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample solution color intensity against platinum-cobalt standard solutions or direct absorbance measurement at 430 nm. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped glass tube filled with the sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index by measuring critical angle of total internal reflection at the prism-sample interface. |
| Melting Point | Capillary Melting Point Apparatus | Thermal analysis of solid-phase transition observed visually through capillary tube as temperature is gradually increased. |
| Organic Volatile Impurities (other than solvents) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by electron ionization and mass spectral identification/quantification using selected ion monitoring. |
