So yesterday I ran three more trials on the spectrometer to measure Sodium. After running about half the trials, I realized I put 1/10 the amount of cobalt I should have. No worries, I just took out the internal standard in the analysis part! Got back 2.81% error of the 0.6 ppm sample and 2.29% error on the 0.8 ppm sample. That was after averaging all the data together. Not too shabby!

ps, can’t get the formatting on that right….
So today we moved on to doing a trial run with out the nucleosomes. Basically making up the samples to be spun and then run in the spectrometer and the calibration set. I struggled all day with the calibrations and the pipets… But it’s all ready to be run tomorrow!
