Frequently Asked Questions

What are Whatman QM-A quartz filter sheets used for?

QM-A quartz microfiber sheets are widely used for air sampling, particulate monitoring, and stack or flue gas analysis. They are especially suitable for PM-10 testing and environmental monitoring where high-temperature stability and low background contamination are required.

What makes quartz microfiber filters better than standard glass fiber filters?

Quartz microfiber filters offer extremely low trace metal content and minimal artifact formation, helping reduce interference from sulfates and nitrates during air pollution analysis. Their high-purity structure also supports sensitive heavy-metal and aerosol testing.

What are the key specifications of the Whatman 1851-865 sheets?

Typical specifications include:

Grade: QM-A
Sheet size: 8 × 10 in (203 × 254 mm)
Material: high-purity quartz microfiber
Pore size: about 2.2 µm
Thickness: ~450–475 µm
Pack size: 25 sheets
Sterility: non-sterile

These features support reliable air sampling and gravimetric analysis workflows.

Can QM-A quartz filters withstand high temperatures?

Yes. QM-A quartz filters can tolerate very high operating temperatures (up to about 800 °C), making them ideal for applications that involve ignition, high-temperature sampling, or thermal analysis.

What industries commonly use QM-A quartz air sampling filters?

These filters are commonly used by environmental monitoring labs, industrial hygiene teams, emissions testing facilities, and research laboratories that require high-purity particulate collection and accurate gravimetric measurements.
