Today,John "the veteran" made solutions of magnesium, cobalt and phosphorus of unknown concentrations and our task was to use results from the spectrometer to make good estimates of their concentrations. We started off by making calibrations of the same solution varying from 1ppm(parts per million) to 9ppm.
We then ran these calibrations in the machine along sides johns samples so we could use our calibrations to deduct the concentrations of his solutions. This was another opportunity for us to improve our pipetting skills. Ben taught me how to pipette properly after he noticed that I was unknowingly drawing out to much solution each time.
We ended up getting the right answers to the concentrations of johns mysterious solutions.We are looking forward to the next task.
