Product specs
Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Silica Gel. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
Product overview This chromatographic silica gel is a white, porous powder primarily composed of silicon dioxide. It is intended for separation and purification processes based on differences in adsorption and retention.
More strongly adsorbed components remain on the silica gel longer, while less strongly adsorbed components elute more readily through the column. The stated reference specification identifies a particle size of 40–63 μm, with at least 80% of the material falling within the qualified size range.
It also lists an average pore diameter of 55–65 Å, a specific surface area of 420–550 m²/g, and a pore volume of 0.65–0.85 ml/g. The listed SiO₂ content is at least 98.5%. Potential uses Supported uses include column chromatographic separation, thin-layer analysis, adsorption treatment, and use as a physical desiccant.
The material is also described for chromatographic purification in petroleum processing, herbal-material separation, and organic-synthesis workflows. Suitability and achievable separation results depend on the sample, solvent system, column conditions, loading, and required purity.
Reference quality parameters The supplied reference limits include pH 6.5–8.0 for a 100 g/L preparation in a 10% aqueous suspension, chloride no more than 0.02%, ferric salts no more than 0.02%, and weight loss after heating at 150°C no more than 5.0%.
Buyer confirmation before procurement The available information contains different purity descriptions, including 99.5% in the product heading, 99% minimum in a general specification field, and at least 98.5% SiO₂ in the detailed reference specification.
Buyers should therefore confirm the exact grade, guaranteed SiO₂ assay, test method, and batch certificate before ordering.
Also confirm the required particle-size distribution, pore properties, moisture or loss-on-heating limit, packaging configuration, storage conditions, shelf-life basis, and whether the selected grade is appropriate for the intended chromatographic method.
Pilot testing is advisable where separation performance is process-critical.
