Strength for Environmental Analysis

Grade GF 9 borosilicate glass filters can be used in a range of environmental analysis applications. The added strength of the inorganic binder makes these filters appropriate for use in retention of samples with heavy particles. Other applications include:

  • Determination of PCB*, DDE, DDT, furans, and dioxins in air
  • Pollution measurements in industrial, urban, and populated areas
  • Dust measurements in the workplace
  • Determination of dust fraction in technical gases
  • Testing the effectiveness of dust-collecting

  • Application : Used in the filtration of coarse particles. Frequently used in environmental analysis, in the determination of PCB, DDE, DDT, furans and dioxins in the air; pollution measurements in industrial, urban and populated areas, cement factories, iron and steel industry, dust measurements at the workplace, determination of the dust fraction in technical gases, and testing the effectiveness of dust-collecting.
