We got the results today and it was another disappointment. The Na concentration was fluctuating while the Mg concentration seemed better but not still up to expectation. Professor Andresen decided to check the parts of the spectrometer again to see if there is any problem wrong with it and he also personally made some solutions to see what happens. Ben and I also started working on our slide show for the presentation we have tomorrow. We are gathering our data and doing some final analysis on them.
