Filtering device - filter membrane for manual monitoring of PM2.5 in air

Filtering device - filter membrane for manual monitoring of PM2.5 in air

Microporous membrane materials include mixed cellulose (MCE), cellulose acetate nylon (PA/NYLON), polypropylene (PP), polyether sulfone (PES), polyvinylidene fluoride (PVDF)

Polytetrafluoroethylene（PTFE）Material, regenerated cellulose（RC）Material, polycarbonate（PCmembrane,Nuclear drilling material, fiberglass（GF）Material, etc.

Mainly used for sample analysis, especially for mobile phase and sample filtration in chromatographic analysis,It has a good effect on protecting the chromatographic column, pipeline system, and injection valve from contamination.

It has been widely used in weight analysis, microanalysis, colloid separation, and sterile experiments.

Product Features:

Compliant with US EPA40 CFE part 50, Appendix L

Each film strip is numbered sequentially

The extremely low dissolution and fluorescence background make it suitable for elemental analysis
