- Note:DSC did not have the attached gas and was unable to be used. Prepared samples will be run and the data will be collected when next in the labaratory
Atomic Absorption
- Solutions run were prepared on 2012/09/21
- The General Protocol for AA described on 2012/10/05 was used

Calibration Curve
General Notes:
- The standards used were too high of a concentration. Need to remake CuSO4 standards between 5-20ppm.
- All Fe3O4 samples need to be reprepared and retested. Solutions were prepared with CuSO4 instead of deionized H2O. Concentrations were inaccurate and calibration curve created was inaccurate
- AA needs to be run again
