Nut Shell Activated Carbon: Confirm the Feedstock
Resolve nut-shell and fruit-shell sourcing labels by naming the shell material, supplied form and application. No generic shell label proves a grade.
Clarify a nut-shell activated-carbon inquiry by naming the required shell material, supplied form and application. GBL's fruit-shell page lists peach, apricot, jujube and walnut shell feedstocks. Its product-family guidance asks buyers to confirm the form on inquiry, so a general shell label should be followed by a specific product description in the offer.
What should a nut-shell activated-carbon quotation identify?
Ask the supplier to state the shell material used for the proposed grade and the actual supplied form. Request the particle-size specification, then keep the feedstock description with the quoted form and specification. Use the exact product identity from the offer when reviewing what is being supplied, rather than treating a general shell label as a grade description.
What should be checked before specifying walnut-shell GAC?
Request an explicit feedstock description for the offered grade because the public shell page lists multiple shell materials. Ask the supplier to state the supplied form in the quotation; the product-family guidance leaves that point for inquiry. Send the intended treatment duty and request the grade specification with supporting test data for that application.
