Description:
Cytiva Whatman 1851-047 QM-A 4.7cm Quartz Microfiber Air Sampling Filters. These high-purity quartz microfiber filters are used in many air sampling filter applications, including sampling of acidic gases, stacks, flues, and aerosols. Filters are suitable for PM-10 sampling and analysis. 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. 100/pack.
- Temperature resistant up to 800°C
