Quantitative Ashless Filter Paper - CF15009
Quantitative methods where the filter is ashed alongside the sample require documented, ultra-low residue to protect analytical accuracy. Gravimetric analysis demands filter paper that contributes virtually no residue after ignition, ensuring mass measurements reflect the sample alone. In sum, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.
Key Filter Paper Characteristics
- Ash content of ≤0.011% provides the documented blank value specification that quantitative analytical methods require.
- Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.
- Tightly controlled manufacturing produces documented ash content that remains consistent across production lots for method reproducibility.
- Acid washing process removes metallic contaminants that could interfere with trace element determinations after ignition.
- At 16um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
When your analytical procedure specifies a particular grade, the retention and purity characteristics documented above confirm method compliance. Premium cellulose purity reduces the blank correction calculations your gravimetric procedures would otherwise require. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
