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!
| Sample ID |
Calc Conc | Actual Conc | SD | % Error |
| Average | ||||
| Sam 1 NaCo | 0.5811 | 0.598 | 0.005 | 2.812361468 |
| Sam 2 NaCo | 0.8173 | 0.799 | 0.00636 | -2.29319108 |
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!
