Description

General description

Filter Code: FMLW

Unlike fibrous filter media that trap particles in their matrix, Fluoropore^® (hydrophobic PTFE) membranes collect particles on their surface, which make them ideal candidates for use in airborne particle monitoring applications. This surface collection provides better detection efficiencies and lower FWHM measurements. (FWHM is defined as the full width at half of the maximum height of the P0-218 peak obtained during sampling of room air.)

•High collection efficiency
•Extremely low pressure drop
•Higher throughput capacity
•Black backing ensures proper orientation

Choice of Pore Sizes:
Fluoropore membranes are available in 3 µm (FSLW) and 5 µm (FMLW) pore sizes - the smaller pore size provides low FWHM; the larger pore size has very low pressure drop and greater throughput capacity, which minimizes the number of filter changeouts.

Contrasting Backing Material:
The white backing of our FMLW filter is gridded to assist in identifying membrane orientation for the correct installation into sampling devices.

Application

• Clarifying acids, bases, and solvents
• Filtering or venting gases
• UV spectroscopy
• Particle monitoring
• HPLC, UPLC, LC-MS/MS mobile phase filtration
• Microplastics analysis
