Week 2 Lecture 4 9/7/16 Mass spectrometry - Mass spectrometry is how we determine the percentages of each naturally occurring isotope - Magnetic field separates ions based on ratio of mass to charge Uncertainty and Significant Figures - When a measurement is made, there is always some uncertainty, because we can only approximate the measurement - Cost of measurement, different measuring tools cost different amounts the more accurate of the measurement or further out in decimal places, the more expensive the device. - This last digit is an estimate and is said to be uncertain
