Industrial Adsorbent RFQ Checklist: What Buyers Should Send Before Quotation
01Price checkConfirmed material or grade, particle size, quantity and destination
02Technical selectionApplication, target, operating conditions and performance requirement
03Replacement orderExisting media, vessel or process information, filling amount and current issue
A useful adsorbent quotation starts with the application and purchasing requirement, not only the material name. Buyers should provide enough information to identify the correct product family, grade direction, particle form, operating duty, quantity, packaging and document requirement before price comparison.
This checklist covers the minimum RFQ data for molecular sieves, activated alumina, activated carbon, silica gel, activated molecular sieve powder and catalyst-support materials, including replacement projects where the existing product information is incomplete.
Quick Answer: What Information Is Needed for an Adsorbent Quote?
For an initial adsorbent quotation, send the application, required material if known, particle size or form, required quantity and destination country. If product selection or replacement matching is required, also send the process medium, target contaminant or molecule, operating pressure, operating temperature, flow or treatment volume, equipment information, existing product data and required outlet performance.

| RFQ Level | Minimum Data | When It Is Enough |
|---|---|---|
| Initial Price Check | Product/material, particle size or form, quantity, destination | When exact product specification already confirmed |
| Product Selection | Application, process medium, target, pressure, temperature, flow, performance target | When correct grade not confirmed |
| Replacement Project | Existing grade, particle size, filling quantity, equipment data, current problem, operating conditions | When replacing media in existing equipment |
| Document Review | TDS, SDS, COA, packing requirement, export document requirement | When technical approval or purchasing documentation required |
Minimum Information for an Initial RFQ
Not every inquiry needs a complete engineering data sheet. If the product is already confirmed, a short commercial RFQ may be enough.
Product Information
- Product name/family
- Grade/model if known
- Particle form
- Particle size/mesh
- Existing reference/spec if applicable
Commercial Information
- Required quantity
- Packaging
- Destination
- Trade term if known
- Required documents
- Sample requirement
Application Information
- Application/process
- Target contaminant/molecule
- Required performance
- Equipment type
- Replacement/new filling
Send the minimum confirmed information first. Additional process or equipment data can be reviewed when grade selection, performance review or replacement matching is required.
RFQ Data by Adsorbent Product Family
Different adsorbent families require different purchasing and technical data. Do not send the same generic checklist for every product.

Operating Data That Changes Adsorbent Selection
Operating information helps distinguish a basic price check from a product-selection or replacement review. Send the data that is available and identify any values still being confirmed.
Swipe horizontally to review the complete table →
| Operating Item | What to Send | Why It Matters |
|---|---|---|
| Process Medium | Gas, liquid, formulation or mixed stream | Defines environment contacting adsorbent |
| Feed Composition | Main components and known contaminants | Helps identify competing adsorption or chemical compatibility |
| Target | Moisture, CO2, H2S, odor, VOC, color, fluoride, oxygen/nitrogen separation or other target | Defines required function |
| Flow / Treatment Volume | Gas flow, liquid flow or batch volume | Connects media requirement with equipment duty |
| Pressure | Normal operating pressure and max if relevant | Important for PSA, gas drying/fixed-bed |
| Temperature | Normal inlet / adsorption / regeneration temp | Can change adsorption/regeneration |
| Performance Target | Dew point, purity, concentration, color, odor or other result | Defines acceptance target |
| Cycle / Regeneration | PSA, TSA, heatless, heated purge, batch or non-regenerative | Affects grade/loading |
| Equipment | Dryer, vessel, filter, tower, reactor or package | Physical context |
Extra Data Needed for Replacement Projects
Replacement projects need more than a generic product name. Existing media, filling data, equipment conditions and the current operating problem help establish a useful comparison basis.
Existing Media Data
- Existing product/grade
- Particle form
- Particle size
- Existing filling quantity
- Original label/TDS if available
- Last replacement date
- Service history
Equipment & Problem Data
- Equipment manufacturer/model
- Vessel diameter
- Bed depth
- Support layer
- Operating conditions
- Current performance
- Current problem
- Replacement reason

Common RFQ Mistakes That Delay Quotation
Sending only a generic product name.
Names such as molecular sieve, activated alumina or activated carbon can cover multiple grades and forms. Add the application and particle information where possible.
Sending only the quantity.
Quantity supports pricing, but it does not identify the product direction. Include the required material or intended process.
Sending only a product photo.
A photo can support identification, but it normally does not replace grade, size, application or technical data.
Ignoring particle size.
Particle form and size affect handling, pressure drop, loading and equipment fit. State the existing or required size if known.
Omitting destination and packaging.
Destination, package format and quantity are needed to establish a practical export quotation basis.
Requesting “same replacement” without equipment data.
Replacement matching should consider the existing media, operating duty, equipment and current problem rather than appearance alone.
Frequently Asked Questions
What is the minimum information needed for an adsorbent quote?
Send the application, product or material direction if known, particle size or form, quantity and destination country. Add operating or equipment data when selection support is required.
Can I request a quote without knowing the exact grade?
Yes. Send the application, process medium, target, operating conditions and quantity. The product family and grade direction can then be reviewed.
Is a product photo enough for an RFQ?
A photo may help with initial identification, but grade, size, application, quantity and destination are still needed for a useful quotation basis.
Why is particle size important?
Particle size affects loading, pressure drop, mass transfer, handling and equipment fit. Existing or required size should be included where available.
What data is needed for a replacement project?
Send existing grade, particle form and size, filling quantity, equipment information, operating conditions, current performance and replacement reason.
Are TDS and COA needed before quotation?
They may be needed for technical approval or document review. State the required document scope and confirm applicable documents for the product grade.
Can I request a quote for several adsorbent products?
Yes. List each product family, application, quantity, destination and document requirement so each route can be reviewed clearly.
What if some technical data is unavailable?
Send the information already confirmed and identify the missing items. A short initial RFQ can be expanded when selection or replacement review is needed.
