Quartz Depth Filters
Quartz depth filters are used for sampling for elemental/organic carbon, Diesel Particulate Matter (DPM) and trace-level contaminants.
- Heat treated to reduce trace organics
- Binder free for maximum purity
- Low metal background
- Will withstand temperatures up to 1000°C (1832°F)
Filter Type
- Type R-100 Filters meet specific requirements set forth by NIOSH - 99.97% retention efficiency for 0.3 µm diocrylphthalate (DOP) particles up to a 200 mg filter loading.
- Tissuquartz™ Filters have a typical retention efficiency of 99.90% for 0.3 µm DOP particles at 32 L/min per 100 cm2 filter media.
