ANALYSIS OF EARS POWDER
1.0
SAMPLE
One plastic bag containing a fine white
powder was received for identification and heavy metals analysis.
0METHODOLOGY
AND RESULTS
The sample was analysed directly by X-Ray Diffraction Spectroscopy to identify the mineral matter in the sample, by X-Ray Fluorescence Spectrometry to determine the elemental chemical composition of the sample and by acid dissolution and ICP/MS for heavy metals. The approximate chemical composition of the powder sample was:
Calcium sulphate (Bassanite) 29%
Magnesium
aluminium silicate (Clinochlore) 30%
Magnesium
silicate (Talc) 25%
Aluminium
sulphate (Millosevichite) 15%
Calcium
carbonate (Dolomite) less than 1%
Mixed
silicate (Edenite) less than 1%
The levels of heavy metals found in the sample were as follows:
Arsenic not detected (<0.01 ppm)
Barium not detected
Cadmium not detected
Chromium 0.25 ppm
Copper 1.47 ppm
Lead not detected
Mercury not detected
Nickel 1.0 ppm
Not detected = less than 0.01 ppm for all elements
ppm = milligrams per kilogram
