Here are some Infrared spectragraphs (ABOVE), that were of the most importance that we will be using to identify the compounds that we will be making in the lab during biofuel production.
Today our group was able to sample some organic compounds with the infrared spectroscope. We practiced preparing a sample, procedures to start up the machine and how to read the graph that comes up. Infrared is on the lower energy end of the electromagnetic end of the spectrum, just under visible light. Our group followed the procedures for using the instrument which is:
1. Sign in on logbook
2. Turn on the electronics with the power strip and load the software with the "EZ" and triangle logo.
3. ensuring the liquid tray is in place, wipe the sample window with chemwipes soaked in methanol.
4. RUN background to cancel the "noise" that may contaminate sample, don't save.
5. Place a drop of sample over window and Click the
6. Save sample, floppy or on H.D.
7. Label peaks, to identify the composition of sample.
8. CLEAN the sample window with chemwipes soaked in methanol.
After the samples, we were able to observe a potential graduate student orally defend her thesis project. Talk about the "HOT SEAT"!!!!
