Marissa at Work



Marissa De Fratti prepares her first of five samples of 1-octene to scan on the Infrared Spectrometer (IR). Different solutions with different amounts of 1-octene diluted to 100 ┬ÁL with methanol. The results of the scans are spectras with differing peaks depending on the concentrations of octene within the sample. On average, two to four scans of each sample is taken because of instrumental error. The data from the spectras is taken and then graphed in kaleidagraph. If the error is somewhere between 1 and .90, then the data is acceptable. By doing this she hopes to find that the IR is quantative enough so that it can be used to examine simple reaction mixture analysis in ATRA.
