Binder-free Quartz Depth Filters offer superior purity for the collection of elemental/organic carbon, DPM, and trace-level contaminants. Tissuquartz and Type R-100 Quartz Filters are heat treated to reduce trace organics and feature a low-metal background. Look for Quartz Filters as bulk filters or in preloaded cassettes to meet NIOSH Method 5040 or 7908.
