Manufacturing Quality Control of POLYETHERIMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Intrinsic Viscosity | Capillary Viscometry | Measures solution flow time through a capillary to calculate intrinsic viscosity, reflecting polymer molecular weight. |
| Glass Transition Temperature (Tg) | Differential Scanning Calorimetry (DSC) | Detects heat flow difference between sample and reference during controlled heating to identify Tg endothermic transition. |
| Moisture Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction of iodine with water in a methanol-based reagent. |
| Residual Solvent Content | Gas Chromatography (GC) | Separates and quantifies volatile solvents using a capillary column and flame ionization detection. |
| Ash Content | Gravimetric Analysis (High-Temperature Ashing) | Determines inorganic residue mass after combustion at 550-600 C in a muffle furnace. |
| Chloride Ion Content | Ion Chromatography (IC) | Separates and detects chloride anions based on ion exchange and conductivity detection. |
| Heavy Metals (Pb, Cd, Cr, Hg) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in plasma; measures element-specific emission wavelengths. |
| Acid Number | Potentiometric Titration with NaOH | Determines free carboxylic acid groups by titration with standardized sodium hydroxide solution. |
| Color (APHA) | Visual Comparison or Spectrophotometry (430 nm) | Measures yellowness intensity relative to platinum-cobalt standards using absorbance at 430 nm. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity pattern to calculate particle size distribution in dispersed powder. |
| Thermal Decomposition Onset Temperature | Thermogravimetric Analysis (TGA) | Monitors mass loss as a function of temperature under inert atmosphere to determine decomposition onset. |
| Melt Flow Rate (MFR) | Melt Flow Indexer (ASTM D1238) | Measures extrudate mass in grams per 10 minutes under specified temperature and load conditions. |
