| Industry | Application | Process |
|---|---|---|
| Food Industry | Nutritional fortificant (calcium source) | Direct addition or blending |
| Pharmaceutical Industry | Calcium supplement (for treatment or prevention of calcium deficiency) | Formulation processing (tablets, capsules, etc.) |
| Dietary Supplement Manufacturing | Dietary supplement (supporting bone health) | Blending and tablet compression |
| Oral Care | Toothpaste additive (caries prevention and enamel remineralization) | 膏体混合与灌装 |
| Animal Feed Industry | Calcium fortification in animal feed | Premix feed preparation |
| Test Item | Common Test Methods | Method Summary |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with the standard spectrum to confirm the presence of characteristic functional groups of calcium glycerophosphate (e.g., P–O, C–O, and Ca²⁺-related vibration peaks). |
| Calcium Ion Identification Test | Add ammonium oxalate solution to form a white precipitate of calcium oxalate; or perform a flame test, which produces a brick-red flame, confirming the presence of calcium ions. | |
| Phosphate Ion Identification Test | In acidic conditions, add ammonium molybdate reagent and heat to produce a yellow ammonium phosphomolybdate precipitate, confirming the presence of phosphate ions. | |
| Assay | Complexometric Titration (EDTA Titration) | Based on the principle that EDTA forms a stable complex with calcium ions, titrate the sample in a buffer solution at pH ~10 using Eriochrome Black T or calcium indicator to determine calcium content, then calculate calcium glycerophosphate content indirectly. |
| Ion Chromatography (IC) | Separate and quantify phosphate ions in the sample. Combined with calcium content results, verify the composition ratio and purity of calcium glycerophosphate. | |
| pH Value | pH Meter Method | Prepare a specified concentration of aqueous solution (e.g., 1%), measure pH using a calibrated pH meter, and assess whether acidity/alkalinity meets quality specifications (typically near neutral). |
| Loss on Drying | Gravimetric Loss upon Drying | Dry the sample at 105°C to constant weight and determine the percentage weight loss, used to control moisture and volatile content. |
| Sulfated Ash / Residue on Ignition | Residue on Ignition Test | Ignite the sample at high temperature (~600–800°C) and weigh the residual inorganic matter to evaluate total inorganic impurities. |
| Heavy Metals | Thioacetamide Method (or Atomic Absorption Spectroscopy) | Use the pharmacopoeia-specified thioacetamide colorimetric method or more sensitive atomic absorption spectroscopy (AAS) to detect whether heavy metal elements such as lead, cadmium, mercury, and arsenic exceed permissible limits. |
| Microbial Limits | Microbiological Culture Method | Perform total aerobic microbial count, mold and yeast count, and tests for specified microorganisms (e.g., *Escherichia coli*, *Salmonella*) according to the *Chinese Pharmacopoeia* or relevant standards to ensure microbial contamination is within acceptable limits. |
| Water-Insoluble Matter | Gravimetric Method | Dissolve the sample in water, filter, dry the residue, and weigh it to calculate the water-insoluble content, reflecting product purity and process-related impurity levels. |

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?
