TFH-01/47 PTFE Filter/TFH membrane

Overview

New construction resolves many of the problems associated with the demanding usage environment for PM sampling filters.

Features

  • Combines the excellent collection ability of a PTFE filter with a breathable reinforcing layer of non-woven fabric.
  • Reduces absorbency and conductivity and also prevents post- collection dispersal of samples.
  • Ensures superior release performance of the PM after collection (effective in micro-chemical analysis of composition).
  • Allows smaller filter unit weights than with the standard glass fiber paper used in automatic PM measurement devices (β-ray absorption method). This has improved detection sensitivity by approximately five times compared to previous HORIBA units.
  • Strengthens chemical resistance to acids, alkalis, and organic solvents.
  • Decreases filter weight and also allows accurate weight measurement of low-concentration samples.
  • Greatly lowers the chemical background, eliminating interference and allowing chemical analysis of composition (water-soluble components, organic compounds, metal components, etc). Patent pending
