| Industry | Application | Process |
|---|---|---|
| Textile Industry | Dyes | Used in reactive dyeing |
| Plastics Industry | Colorants | Used in injection molding |
| Coatings Industry | Colorants | Used in paint formulation |
| Paper Industry | Colorants | Used in pulp sizing |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic wavelength using Beer-Lambert law with reference standard. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Determines inorganic residue after high-temperature combustion and subsequent weighing of residual ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies lead and other heavy metals by measuring absorption of specific wavelengths of light by ground-state atoms in flame or graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via precipitation titration with silver nitrate, using silver indicator electrode to identify endpoint. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in standardized aqueous dispersion using calibrated glass electrode system. |
| Water Solubility | Visual Inspection and Filtration | Assesses complete dissolution in specified volume of water at defined temperature; absence of undissolved particles after filtration indicates compliance. |
| Organic Impurities (Related Substances) | High Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related impurities using reversed-phase column and UV detection against reference standards. |
| Iron Content | ICP-OES | Determines trace iron by measuring intensity of element-specific atomic emission lines after plasma atomization and excitation. |
| Sulfate Content | Gravimetric Analysis (BaSO4 Precipitation) | Quantifies sulfate as insoluble barium sulfate precipitate formed after acidification and addition of barium chloride, followed by drying and weighing. |
| Bulk Density | Graduated Cylinder Method | Measures mass per unit volume of freely poured powder using standardized cylinder and tapping procedure per ASTM D1895. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles in liquid or air. |

1. How do you ensure product quality consistency?
We rely on a mature China-based manufacturing system and implement strict batch control and quality inspection for every shipment. Our production process complies with ISO 9001 standards, and a COA is provided for each batch to ensure consistent and reliable quality.
2. Do you offer competitive pricing for bulk orders?
Yes, as a China-based manufacturer and bulk supplier, we provide tiered pricing based on order volume. We support FOB and CIF quotations, as well as L/C payment terms for large transactions to meet international trade requirements.
3. Can you support large-volume or long-term supply?
We have stable production capacity and a well-established supply chain, enabling continuous bulk supply. We support ton-level and container-level orders, as well as long-term cooperation projects.
4. What is your typical lead time?
For in-stock products, shipment can be arranged within 1–3 days. For bulk packaging or customized orders, lead time depends on the specific quantity and production schedule.
5. What documents do you provide?
We can provide complete documentation upon request, including COA, SDS, TDS, and other compliance certificates, meeting industrial procurement and export requirements.
6. Can you customize product specifications or packaging?
Yes, we support customization of parameters such as purity, impurities, residual solvents, and heavy metals. We also offer various bulk packaging options, including 25kg bags, drums, and IBC tanks, suitable for industrial applications and transportation.
7. What shipping options do you support?
We support both FCL (Full Container Load) and LCL (Less than Container Load) shipments, and can flexibly arrange logistics solutions based on order size to meet bulk chemical export needs.
8. Do you provide technical or application support?
Yes, we provide basic application guidance and technical support based on industry experience to help customers optimize product usage.
9. How do you handle compliance and export regulations?
We are familiar with international trade and export regulations, ensuring all products comply with relevant requirements. We also provide complete documentation to support smooth customs clearance and global delivery.
