Description
Cytiva's Whatman Grade 41 environmental pollution papers are among the fastest filter papers in the Whatman ashless range. This gravimetric filter is well suited for quantitative analysis of soil and air.
- Extremely low ash content (0.007% ash maximum)
- 20 µm nominal particle retention rating
- Fast filtration speed (Herzberg 54 s)
- Commonly used for routine air pollution analysis and soil pollution analysis
Fast ashless paper for pollution analysis
Whatman Grade 41 filters from Cytiva's business are suitable for quantitative air pollution analysis as a paper tape for impregnation when determining gaseous compounds at high flow rates.
Grade 41 filters are also commonly used in preparing solid environmental samples (e.g., soils, sludges) for metals analysis after nitric acid digestion.
