Start with the process. GAC is commonly retained in a fixed bed; PAC is dosed and then separated; pelletized grades are used in many gas-phase beds. The contaminant, contact conditions and equipment determine which grades should be tested.

Provide the target contaminants, inlet concentration or analysis, flow or dose, temperature, pH or humidity, equipment dimensions and required outlet. Tell us how you plan to test the sample.

No. Review the relevant adsorption method together with particle size, moisture, ash, density and mechanical properties where applicable. Confirm performance with representative process conditions.

Ask for the technical data sheet for the exact grade, named test methods, agreed specification limits and relevant handling or packing information. Batch data should be tied to the supplied batch where available.

Discuss raw material, particle form, size range, treatment and packing with the application brief. Confirm the proposed grade, sample results and purchase specification before a bulk order.

Send the current grade name or data sheet, operating conditions and acceptance criteria. Compare the proposed material using the same test methods and a representative trial. Similar raw material, particle size or iodine value alone does not establish interchangeability. See the carbon-form comparison checklist.

Share the application and proposed trial method so a representative grade and sample quantity can be discussed. Sample arrangements depend on the specific product and order brief.

Identify the product or grade, trial quantity, intended test and delivery country. Confirm sample availability, any preparation requirements, courier arrangements and who covers freight before dispatch. Use รับตัวอย่างฟรี to send the trial brief.

The selected grade, order quantity, packing or labeling requirements and delivery plan determine the quotation. Ask for the minimum order, pack format, readiness date and shipment terms in writing for your specific order. Include recurring demand when discussing OEM or bulk supply.

Contact us first with your company, discussion topic and proposed date. Confirm the meeting location and appointment before travelling.
