Manufacturing Quality Control of BUTYL RHODAMINE B
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies main component concentration via absorbance at characteristic wavelength using Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Measures water content by electrochemical titration with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Determines total heavy metal content by atomizing sample and measuring absorption of specific elemental wavelengths. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion and sulfuric acid treatment, followed by high-temperature ignition and weighing. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions via precipitation titration using silver nitrate and silver indicator electrode. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode system. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Separates and quantifies residual solvents and volatile organics based on partitioning between mobile gas phase and stationary column phase. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering from dispersed particles in liquid medium. |
| Color Strength (Tinting Strength) | Visual Comparison or Reflectance Spectrophotometry | Evaluates dyeing performance relative to standard by comparing color intensity on standardized substrate under controlled conditions. |
| Water Solubility | Gravimetric Filtration and Drying | Measures undissolved residue after dissolving sample in specified volume of water, filtering, drying, and weighing. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile impurities by ignition at specified temperature and weighing the remaining residue. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume of powder after standardized tapping procedure in calibrated cylinder. |
