Week of 2/17-3/3/17

This week I was trained to use the FTIR. Before I begin to use the machine to take data from the sample; I first, need to make sure that everything is in the right conditions. To prepare for testing, I need to turn on the air valve and hook it to a device that reads the moisture in the air that is being blown through. The chamber of the FTIR needs to have zero moisture since the moisture in the air can interfere with the results. Once the dry air is going through the chamber, I can then turn on the FTIR and pour liquid nitrogen into the second chamber, the one with the microscope, to cool it down.

Once the setup is complete, I check if the FTIR is cold enough by using a computer program. From there I am/was able to begin taking practice sample data to get accustomed to the FTIR computer program and its different functionalities.
