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 GE 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.

Looking for a filter paper, membrane filter, or syringe filter? Let GE help you find the optimal filter for your needs to ensure reliable analysis.
