-Before using any instruments, make sure the lab instructor (TA or professor) has instructed you on its use. DO NOT use any of the instrument unless you are supervised by a lab instructor, graduate instrument assistant, or by a professor. All of these instruments are very expensive, and printing out and reading the directions alone is not enough information to be able to properly use any of the instruments. |
Infrared Spectroscopy
-Infrared (IR) spectroscopy can be defined as the use of instrumentation to measure the ability of matter to absorb, reflect, and transmit infrared radiation (Alpert et al. 1970). To get an idea of the range of radiation infrared encompasses, its region of the spectrum is from 0.78 to 1000 mm (Skoog et al. 1998). -This
nondestructive instrumentation technique can be used for most types
of samples, and is an important tool to many chemists. Though a
molecule can give a complicated chromatogram (the output that is
viewed and/or printed from an IR instrument), this is actually used
to an advantage for identifying different compounds (Silverstein
and Webster, 1998). |
