Zeolite Quality Control
For zeolite catalyst procurement, quality control is not just a laboratory detail. It is how buyers confirm that a batch matches the required framework, composition, acidity, particle size, and application grade before sample approval or bulk purchase.
ZeoCatalyst can provide product documentation such as TDS, COA, XRD, BET, chemical composition, and particle size data based on the ordered grade and testing requirement.
Common Zeolite QC Items
| QC item | Procurement purpose |
|---|---|
| TDS | Confirms standard specification range before sample or order approval |
| COA | Confirms actual batch values for shipment and internal quality records |
| XRD | Verifies zeolite framework and crystallinity |
| BET surface area | Confirms surface area and adsorption/catalyst accessibility |
| ICP or chemical composition | Checks Si/Al ratio, Na2O, metal exchange level, or impurity limits |
| Particle size | Confirms powder handling, dispersion, formulation, or pressure drop needs |
| LOI | Confirms moisture and volatile content before processing |
| Bulk density | Supports packaging, filling, and scale-up calculations |
Documents Buyers Commonly Request
- Technical Data Sheet for standard product specification
- Certificate of Analysis sample for batch-level data format
- MSDS for logistics and internal safety review
- XRD pattern for framework confirmation
- BET and pore volume data for adsorption or catalytic evaluation
- ICP or composition report for Si/Al ratio, sodium content, or exchanged metal level
Quality Questions To Clarify Before Ordering
- Is the product for catalyst formulation, adsorbent testing, ion exchange, or academic evaluation?
- Which values are critical: Si/Al ratio, sodium content, crystallinity, particle size, surface area, or metal loading?
- Do you need powder, extrudate, pellet, or binder-free adsorbent?
- Is the order for lab sample, pilot evaluation, or repeat bulk supply?
- Which documents are required by your purchasing or QA team?
For early evaluation, request a sample with TDS and available batch data. For repeat procurement, define the critical parameters in the quotation request so the COA can match your acceptance criteria.
