CARBON BLACK ANALYSIS

Carbon Black can be the cause of discoloration in buildings.  "Ghosting" along ceilings and studs and blackening effects on carpets and around pictures can be due to airborne carbon black.  Analysis by Transmission Electron Microscopy (TEM) can determine if the material sampled is actually carbon black particles.

Sample collection for airborne Carbon Black should be performed with a 0.1 micron Polycarbonate filter with a minimum volume of 1500 liters.  Dust "wipe" sampling can be performed with a 4x4 inch piece of common "Saran Wrap".  Do not use tissue, paper towel or other fibrous materials.  Bulks can be sampled directly by "Glove bag".  Place samples into "Zip-lock" plastic bags for shipping.

Carbon Black is also used in the manufacture of tires, paints and many other common items.  Evaluation of the component carbon black prior to manufacture can determine if the supplier is meeting your specific requirements.  Analysis after manufacture can determine dispersion, particle size and agglomeration.
