These high purity quartz microfibre filters are used in many air sampling filter applications, including sampling of acidic gases, stacks, flues and aerosols. They are suitable for PM-10 sampling and analysis.

• Binder-free
• High loading capacity

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.
