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
* PCB = polychlorinated biphenyl, DDE = dichlorodiphenyldichloroethylene, DDT = dichlorodiphenyltrichloroethane
