Consumable Filters
Glass Fiber
Those filters are made of high purity borosilicate fibers. Glass fibers filters became, during the last 20 years, the most diffused filtering elements for stack emission and ambient sampling thanks to their low cost but also because of the quality improvement granting better resistance and easier to handle.
They are mostly adopted for particulate matter sampling in every application but can be also used for micropollutants determination such as PCDD/PCDF or PAH. Since they may contain metals, such as, lead, they are not the best solution for heavy metals determination.
