Description

Grade QM-C
QM-C 100% quartz microfiber filter paper features low trace metals (Cr, Ar, Pb, Cd, Ni, Zn) and high temperature resistance. It is well-suited for heavy metal analysis of particulate matter and sampling of acidic gases, stacks, flues and aerosols in air monitors. 100% pure quartz microfiber, without any binder or organic chemicals. Pre-fired filters eliminate firing step, saving time in preparation process. Air retention efficiency >= 99.95% @ 0.3 um DOP. Temperature resistance up to 1200oC. Batch-specific metal report is available on the website for downloading. Certified to conform to European and US EPA standards for heavy metal analysis in air particulate matter. QM-C high purity quartz microfiber filter addresses the challenge of heavy metal analysis in PM2.5/PM10 and enables customers to generate high-quality data. It is also suitable for organic chemical analyses such as PCBs and PAHs.
