What are Whatman ashless quantitative filter papers?
Whatman ashless quantitative filter papers are high-purity filters that support accurate analysis in applications sensitive to very low levels of background contamination and in gravimetric analysis where ash content might affect weight measurements of combusted samples. Cytiva's high-purity Whatman ashless filter papers are suited for:
- Environmental analysis: soil filtration analysis, when separating solid matter from aqueous extracts
- Retention of small particles
- Collection of trace elements and radionuclides from the atmosphere
