EMSL Analytical is the world´s largest laboratory devoted to the analysis of asbestos by electron microscopy. Established in 1981, EMSL became a pioneer in asbestos analysis, refining sample preparations techniques and laboratory practices. In 1984 in an effort to reduce the turnaround on TEM air samples we introduced the currently accepted but then critized 24 hour turnaround; in 1986, same day turnaround time and finally, in 1987, six hour turnaround time. Now EMSL offers 3 Hour Turnaound on TEM. |

POLARIZED LIGHT MICROSCOPY |
|
|
|
Polarized Light Microscopy ( PLM ) is the EPA accepted screening method for asbestos in bulks. However, it fails in samples where asbestos fibers are fine or obscured by tightly binding matrix. |

|
|
PHASE CONTRAST MICROSCOPY |
|
|
|
Phase Contrast Microscopy ( PCM ) is used for measuring fibrous dust greater than 0.3 microns in diameter and greater than 5 microns in length. This methodogy is not capable of identifying asbestos fibers or visualizing fibers less than 0.3 microns in diameter. |

|
TRANSMISSION ELECTRON MICROSCOPY |
|
|
|
Transmission Electron Microscopy ( TEM ) capable of Energy Dispersive X-Ray Microanalysis (EDX) and Electron Diffraction (SAED), is the most sophisticated analytical instrument available to us for the analysis of airborne and waterborne asbestos fibers. Transmission Electron Microscopy is also used for the analysis of asbestos in soils and bulk samples in general. |

SCANNING ELECTRON MICROSCOPY |
|
|
Scanning Electron Microscopy and Energy Dispersive X-Ray Microanalysis(SEM / EDX) is suited for the analysis of asbestos in bulks, tapes, wipes, and for studying the structure and elemental composition of any materials in the solid state.

|
|
X-RAY DIFFRACTION |
|
|
|
X-Ray Diffraction ( XRD ) is used for the analysis of free silica, asbestos in bulks, for product identification and for the identification of crystalline phases in general. |
