A useful sample request defines the suspension and decision before product codes are assigned. Provide enough evidence to choose a small, distinguishable candidate set rather than a generic shipment.
Describe the feed
Include process, particle or precipitate identity, solids, pH range, conductivity, hardness, temperature and relevant metals, coagulants, collectors, frothers or dispersants. State whether the sample represents normal or difficult operation.
Describe the separator and endpoint
Identify clarifier, thickener, settling pond, filter or other equipment. Record flow, solids flux, residence, current chemicals and dose, overflow or filtrate target, underflow or cake target and downstream water reuse.
Plan a fair comparison
Use equal active dose, consistent preparation and repeatable mixing. Include blank, current product, underdose and overdose, then repeat finalists. For coal or mineral circuits, include the downstream beneficiation check where treated water returns.
Complete supply details
Add monthly demand, product form, packaging preference, destination, Incoterm and required documents. Enquiry data goes directly to Xinqi Polymer technical sales for sample coordination and quotation.
Application-based sample request
Put the feed evidence on one sheet.
Include the solids, water chemistry, separator, current treatment, operating target, quantity and destination.
