Anthophylite Finnish = 1 g

The origin of this sample was the Paakilla mine in Finland. This type of asbestos only rarely found in construction materials. The fibers seem to be extremely flat and thin with a characteristic shape that resembles that of a knife blade, coming to a point at one end.

These standard reference asbestos (UICC)* samples "(chrysotile, amosite, anthophylite, crocidolite)" are packaged in 0.1g vials. (That may not sound like much but it is a considerable amount!). For most, it is a "lifetime" supply. These standard samples were developed specifically for calibration, testing, or reference specification for comparison with unknown materials. Use as "knowns" for SAED, EDS, XRD, and for morphological standards for TEM and SEM and sometimes even for LM. However we are unable to issue a Certificate of Conformity for these unique standard samples. SPI Supplies is the exclusive worldwide distributor for these five, one-of-a-kind standard asbestos samples. 

But we can state that the origin of these five very unique and specially characterized samples was Dr. V. Timbrell, Pneumoconiosis Research Unit, Llandough Hospital, Penarth, Glamorgan, United Kingdom with the shipment being made in early 1972.

The trace element compositions of the UICC standard asbestos samples are reported in American Journal of Industrial Medicine Volume 32, Issue 6 , Pages 592 - 594, Published Online: 6 Dec 1998.

 

For further information on the use of the standards, we would suggest reading the following: J. L. Hutchison, M. C. Irusteta and E. J. W. Whittaker, High-resolution electron microscopy and diffraction studies of fibrous amphiboles, Acta Crystallographica, Vol. A31, Part 6, November (1975), p.974-801.

 

Special note for those contemplating asbestos analyses:

We always want to remind anyone planning to do their own analyses, at least in the USA, that there are US government approved procedures for

TEM (NIOSH 7402)

XRD (NIOSH 9000)

 

SPI Supplies also offers the analyst a full range of standards for microanalysis for EDS and WDS being done in an SEM or WDS being done in a free standing wavelength dispersive electron probe microanalysis system.

 

Packaging:

All five asbestos standards are available in glass vials.
