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)

Description

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.
