- Intermediate particle retention rating of 16 µm
- Herzberg filtration speed of 155 s
- Particle collection between that of Grades 40 and 41
Particle Collection and Inorganic Analysis
Whatman Grade 43 can be ashed during gravimetric analysis without contributing substantially to the measured weight. These filters are also appropriate for:
- Inorganic analysis in the construction, mining, and steel industries
- Particle collection for air pollution monitoring for subsequent analysis by X-Ray fluorescence (XRF) techniques
- Soil analysis
- Foodstuffs filtration analysis
