Bondar Clegg (stream sediments) COL (W) - sample fused with Ni crucibles and mix of Na2CO3, NaCl, and KNO3 (5/4/1)



Bondar Clegg, stream sediments; colorimetry (tungsten)- sample fused with nickel crucibles and mixture of Na2CO3, NaCl, and KNO3 (5/4/1)

General Methodology:

Colorimetric methods employing the standard dithiol method were used to measure W.  The sample was fused at 800oC in nickel crucibles along with a mixture of Na2CO3, NaCl and KNO3 (5/4/1).
