Pall Pallfex filter paper 7221, automotive engine exhaust detection filter membrane

Application:

TissuquartzTMFilter membrane, quartz membrane

• After heat treatment to reduce trace organic matter and achieve high chemical purity.
• Applied to high-temperature environments, analyze acidic gases and aerosols.
• High flow rate and high filtration efficiency.
• Ultra pure water rinsing treatment to reduce residual ion content.

FilberfilmTMMembranes

• Economical filter, suitable for various atmospheric sampling scenarios.
• The moisture changes in the air or gas during the atmospheric sampling process will not cause chemical reactions in the filtration membrane.
• Hot fusion can reduce trace amounts of organic matter.

EmfabTMMembranes

• Foldable to facilitate weighing and transportation;
• Each filter membrane is washed with pure water to remove water-soluble residues.
• Low air resistance, suitable for testing critical gas melt adhesive samples, such as diesel exhaust gas
