Dilutions and Spectral Properties of Solutions part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
The purpose of this week's lab is to - prepare calibration standards - use a UV-Vis spectrometer to determine the spectral peaks for several dye solutions, and create a calibration curve - calculate how much of each single-element standard solution is needed to make a multi-element stock solution
Capabilities and Limitations of Geochemical Instruments part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
The purpose of this exercise is to understand the capability and limitations of several instruments (AA, ICP-OES, ICP-MS) used for geochemical analysis. Students compare and contrast the cost, detection limits, etc. of these instruments.
