Whatman 1851-8866 Filter Sheets, 8" x 10" (prenumbered), Air Sampling Quartz QM-A, 100/pk (PN:1851-8866)

These high-purity quartz microfiber sheets are commonly used for air particulate monitoring, stack and flue sampling, and aerosol analysis. They are especially valuable in environmental testing and PM-10 monitoring where high temperature resistance and low background contamination are required.

Each sheet is sequentially numbered to simplify sample identification and traceability during regulated air monitoring workflows. This feature supports EPA-style documentation and helps laboratories maintain organized chain-of-custody records.

QM-A quartz filters are designed for high-temperature applications and can tolerate temperatures up to about 800 °C, making them suitable for gravimetric analysis and processes that involve ignition or thermal treatment.

Because the filter is binder-free and made from high-purity quartz fibers, it offers excellent chemical inertness and minimizes interference from sulfate or nitrate artifacts. This improves accuracy when analyzing acidic gases or trace metals in air samples.

Yes. The 8 × 10 inch QM-A sheets can be cut or used in appropriate holders for many high-volume and specialty air samplers. Their fine capillary structure and high particle retention make them suitable for a wide range of environmental monitoring setups.
