Economical

• Meet NIOSH and OSHA method specifications for monitoring airborne metals and other fibers

• Biologically inert

• Complete dissolution and clearing

• Purity — low artifacts

• Minimal interference in fiber counting

• Standard digestion procedures

• Gridded filters for fiber counting

• Ideal for air monitoring, AAS, and transmitted light microscopy applications

• NIOSH uses MCE membranes to study nanoparticle morphology and elemental makeup
