Manufacturing Quality Control of Inositol
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Uses reversed-phase or hydrophilic interaction chromatography columns for separation of inositol, with evaporative light scattering detection (ELSD) or refractive index detection (RID) for quantification. Offers high sensitivity and good reproducibility. |
| Content Determination | Gas Chromatography (GC) | Sample is derivatized (e.g., silylation) prior to injection, separated using capillary columns, and quantified by flame ionization detection (FID). Suitable for analysis of volatile derivatives. |
| Content Determination | Capillary Electrophoresis (CE) | Separates ionized inositol under high-voltage electric field in a capillary tube, detected by UV or indirect UV detection. Requires small sample volume, low cost, and is environmentally friendly. |
| Impurity Testing | Thin Layer Chromatography (TLC) | Provides rapid screening of impurities; impurity identification based on comparison of retention factor (Rf) values with reference standards. Suitable for preliminary qualitative analysis. |
| Impurity Testing | HPLC-ELSD / HPLC-RID | Shares the same system as content determination; impurities are identified and semi-quantified by comparing retention times and peak area ratios with reference substances. |
| Drying Loss | Drying Method | Dried at a specified temperature (e.g., 105°C) until constant weight; the percentage of mass loss is calculated to assess moisture and volatile component content. |
| Residue on Ignition | High-Temperature Ashing Method | Sample is incinerated at high temperature (e.g., 600–800°C), and the residual inorganic matter is weighed. Used to evaluate total inorganic salts or metal impurities. |
| Heavy Metal Testing | Atomic Absorption Spectroscopy (AAS) | After sample digestion, lead, arsenic, cadmium, mercury, and other trace elements are determined using flame or graphite furnace AAS. Complies with pharmacopoeial or food safety standards. |
| Heavy Metal Testing | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Enables simultaneous multi-element detection with extremely high sensitivity. Ideal for trace heavy metal analysis, commonly used in high-end quality control and export product compliance testing. |
| Specific Rotation | Polarimeter Measurement | Measures the optical rotation of a solution at a defined concentration, used to distinguish chiral isomers (e.g., myo-inositol vs. other isomers) and assess optical purity. |
| pH Value | pH Meter Measurement | A solution of specified concentration is prepared and directly measured using a calibrated pH meter, reflecting acidity/alkalinity that affects stability and solubility. |
| Solubility | Visual Observation / Turbidity Method | Assesses dissolution behavior in specified solvents (e.g., water, ethanol) through visual inspection or turbidity measurement using a spectrophotometer, evaluating physical state and suitability for formulation. |

Industrial Inositol Procurement FAQ
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?
