| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using gradient HPLC with diode-array detection; impurities quantified relative to main peak. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., methanol, acetone, dichloromethane) using capillary GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element determination of heavy metals after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Ion (Cl-) | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| pH of Aqueous Solution | pH Meter Measurement | Direct measurement of pH in a 1% w/v aqueous suspension using calibrated pH meter with glass electrode. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid using calibrated capillary apparatus under controlled heating rate. |
| Loss on Drying | Gravimetric Method | Mass loss measured after drying sample at 105 C for 2 hours under vacuum; reported as weight percent. |
| Bulk Density | ASTM D1895 | Measurement of mass per unit volume of freely settled powder in a standardized cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine particle size distribution based on Mie theory. |
| Residue on Ignition | Gravimetric Ashing | Weight of non-volatile residue remaining after incineration at 600 C for 30 minutes; reported as percent ash. |

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?
