Charcoal

Charcoal Charcoals are non-specific or at least poorly specific adsorbents, exhibiting numerous macro-and transition pores of various diameters, and as a consequence of the large surface areas (800–1000 m2/g) they show a high adsorption activity [415]. From: Journal of Chromatography Library, 1991

Simultaneous Determination of Ruthenium, Palladium,

1996/4/15Inductively coupled plasma mass spectrometry employing isotope dilution quantification (ID-ICPMS) has been applied to determine trace levels of Ru, Pd, Ir, and Pt in geological materials. Accuracy, precision, and reproducibility are better than those obtained by other ICPMS calibration methods. For this purpose, it is important to achieve isotopic equilibrium by use of a microwave oven.

2013/6/1Some of the urine determinations still come back with measurement done with the graphite furnace technique. It would be best for laboratories to standardize their methodology and standard values. In terms of normal values, I believe that the mean normal for nonexposed subjects 2 SDs should be referenced, as well as the biological exposure index (BEI) with an explanation of what the BEI is.
