Today, Lauren and I finished our calibration samples in the morning. We tried to reduce our errors as much as possible. After lunch, we figured out the adjusted concentrations in our samples. When we both finished, we were introduced to the spectrometer. However we had trouble with the computer system. Lauren and I both met with Professor Andresen individually and he told us what experiments he has planned for us this summer. To finish the day, Lauren and I read more articles.
