| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| SrHPO4 Content | Acid-Base Titration | Quantifies SrHPO4 by titration with standardized HCl after dissolution and pH adjustment. |
| Strontium (Sr) | ICP-OES | Measures Sr concentration via atomic emission intensity of Sr ions in plasma. |
| Phosphorus (P) | UV-Vis Spectrophotometry (as ammonium phosphomolybdate) | Determines P by measuring absorbance of blue molybdenum blue complex at 880 nm. |
| Loss on Ignition (LOI) | Gravimetric Analysis | Measures mass loss after heating to 950 C to assess volatile content and hydration. |
| Water Insolubles | Filtration and Gravimetry | Quantifies undissolved residue after hot water extraction and drying. |
| Chloride (Cl) | Potentiometric Titration (with AgNO3) | Detects Cl- by measuring potential change during silver nitrate titration. |
| Sulfate (SO4) | Gravimetric Analysis (as BaSO4) | Precipitates SO4 as barium sulfate and determines mass after ignition. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Measures total heavy metals by atomic absorption of lead at 283.3 nm after acid digestion. |
| pH of 10% Aqueous Slurry | Potentiometric Measurement | Determines acidity/basicity using calibrated pH electrode in suspension. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution based on angular scattering pattern of laser beam through dispersed sample. |
| Bulk Density | Volumetric Gravimetry | Calculates mass per unit volume using standardized cylinder and tapping procedure. |
| Residue on Ignition (Ash) | Gravimetric Analysis | Measures non-volatile inorganic residue remaining after high-temperature combustion. |

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.
