Filtry z włókna kwarcowego QM-A

Filtry z mikrowłókien kwarcowych o najwyższej czystości stosowane w wielu aplikacjach próbkowania powietrza, w tym gazów kwaśnych, kominowych, spalin oraz aerozoli. Filtry stosowane w próbkowaniu i analizie pyłu zawieszonego PM10.
GE’s 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.

• Temperature resistant up to 800°C
• Binder-free

GE Healthcare’s Life Sciences business offers three types of quartz fiber filters.

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 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.
Application Used for air sampling in acidic gases; stacks; flues and aerosols; particularly at high temperatures up to 500° C and in PM-10 testing.Filters for Use in US EPA PM10 Ambient air monitoring.
