Description
Cytiva's high-purity quartz microfiber filters are used in many air sampling filter applications, including a sampling of acidic gases, stacks, flues, and aerosols. Filters are suitable for PM-10 sampling and analysis.
Whatman quartz microfiber filters
Because of the low level of alkaline earth metals, "artifact" products of sulfates and nitrates (from SO₂ and NO₂) are virtually eliminated. High-purity quartz microfiber filters are therefore applicable for particulate monitoring and heavy metal analysis.
Whatman QM-A filter circles and sheets
QM-A quartz microfiber filters from Cytiva come in a wide range of circle diameters, as well as 25-piece sheets. QM-A sheets (1851-8866) are sequentially numbered according to U.S. Environmental Protection Agency (EPA) standards and are suitable for most applications.
Features
- Temperature resistant up to 800°C.
- Binder-free.
