Mixed Cellulose Ester (MCE) Filters
Hydrophilic, autoclavable, standard filter for fibers and metals
- Economical
- Meet NIOSH and OSHA method specifications for monitoring
airborne metals, asbestos, and fibers
- Biologically inert
- Dissolve and clear completely
- Pure - low artifacts
- Minimal interferences in fiber counting
- Standard digestion procedures
- Ideal for air monitoring, AAS, and transmitted light
microscopy applications
The standard filter for most aerosol sampling in industrial hygiene
applications, mixed cellulose ester (MCE or MEC) membrane filters
are comprised of pure, biologically inert mixtures of cellulose acetate
and cellulose nitrate. MCE membranes are naturally low in metal background
and are compatible with dilute bases and acids and aromatic and aliphatic
hydrocarbons. MCE filters are hydrophilic and wet easily with water
Airborne Metals - NIOSH 7300, OSHA ID121, 125G
SKC MCE membranes meet NIOSH specifications for the collection
and analysis of airborne metals. MCE is easily digested by dilute
nitric acid which makes it ideal for atomic absorption spectroscopic
analysis.
Asbestos Fibers - NIOSH 7400, OSHA ID160
MCE pore structure collapses when exposed to acetone vapor and offers
minimal interferences in fiber counting. This makes it highly suitable
for the collection and analysis of asbestos and other fibers. See
preloaded MCE filters for asbestos.
Additional applications include monitoring some pesticides and fluorides. See
the SKC Air Sampling Guides for further applications.

A typical filter will have a rough side and a shiny side. The shiny side is
easier to read under a microscope, therefore, expose the shiny side to the
air for microscopic analysis. The rough side holds dust more effectively; expose
the rough side for gravimetric analysis.
