1851-118 Quartz Fiber Filter Paper QM-A 118mm

Quartz fiber filter paper

QM-A

High purity quartz (SiO2) fiber filter paper can be used for air sampling in acidic gases, flues, flues, and aerosols, and can withstand high temperature environments up to 800 ° C. It is suitable for PM2.5/PM10 analysis and trace metal element analysis. Filter paper with low alkali metal content can effectively avoid chemical reactions with sulfides and nitrides in the atmosphere during production. QM-A, numbered according to EPA standards, is suitable for most applications.

QM-H

This is a pure quartz fiber filter paper with low heavy metal content, which can be used in environments above 900 ℃.

QM-B

QM-B is a thicker quartz fiber filter paper than QM-A, which has a higher load capacity and is suitable for air sampling. QM-CQM-C is made of 100% quartz fiber without any adhesives or additives. After high-temperature preheating, it can withstand a high temperature environment of 1200 ° C.

QM-C

There is an ultra-low background of metal elements (such as Cr, Ar, Pb, Cd, Ni, Zn), which is suitable for high-temperature environment testing and trace heavy metal analysis of fine particulate matter.
