SPI Supplies Crocidolite Asbestos Analytical Standard Sample
Crocidolite South African
UICC NB #: 4173-111-3
CAS #: 12001-28-4
The origin of this sample was the Koegas mine which was the largest asbestos mine in the Northern Cape of South Africa. This mineral is predominantly made up of hydroxy silicates of Na, Mg, and Fe.
The UICC reference samples* were developed a number of years ago, as part of a world-wide research effort. A relatively large amount of these material were obtained, homogenized, characterized and distributed to a number of end users, manufacturers and sub-distributors. A great deal of analytical data was indeed developed on them for a variety of purposes, and various results were published in a number of different scientific journals and trade publications. 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.
