Manufacturing Quality Control of 1-trimethylsilyloxy-3-trimethylsilylprop-2-yne
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against certified reference standard. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatiles are equilibrated in headspace vial and analyzed via GC-FID or GC-MS. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous medium. |
| Acid Number | Acid-Base Titration (NaOH in methanol) | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride anions using conductivity detection after ion exchange. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Atomization and ionization in plasma; elemental detection based on mass-to-charge ratio. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated to 700-800 C; residue weight measured after cooling in desiccator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color to platinum-cobalt standard solutions using visual match or spectrophotometer. |
| Density | Digital Density Meter (Oscillating U-tube) | Measures density via resonant frequency shift of vibrating U-tube filled with sample. |
| Refractive Index | Refractometry (Abbe Refractometer) | Determines refractive index by measuring critical angle of total internal reflection. |
| Flash Point | Tag Closed Cup Tester | Minimum temperature at which vapors ignite momentarily when exposed to flame under controlled conditions. |
| Viscosity | Capillary Viscometer (Kinematic) | Measures flow time through calibrated capillary tube under gravity; calculates kinematic viscosity. |
