Quartzfibre thimblefilters MK360 Micro-Quartz Fiber Thimbles made of micro-quartz fibers are used for emission testing in high temperature environments (up to 900°C). Unlike microglass fiber, micro-quartz may also be used for the analysis of acidic gases. Quartz meets the highest purity requirements due to the lowest possible heavy metal content.

EUSAAR2, IMPROVEA and NIOSH870 are three frequently used protocols and therefore included in our comparison.

The samples were collected at the same places as for microorganisms.
