Microsoft Software Box WrapperCHFEN 5503 IR/FTIR Spectra and Analysis Lab Spring 2004STUDENT OBJECTIVESThis series of lab exercises is intended to give you:1. An opportunity to use the P.E. 1600 FTIR spectrometer.2. Experience acquiring FTIR spectra for gases, solid films, and neat liquids.3. An opportunity to relate IR spectra to chemical structure.4. An opportunity to "solve" analytical problems using FTIR.INTRODUCTION The successful use of the Perkin Elmer (P.E.) 1600 FTIR includes understanding procedures for the instrument, the computer software, and sample preparation. The P.E. is also capable of being controlled from the touch pads on the instrument. Your objective is to learn the basics of the FTIR instrument, including startup, scanning, saving and printing a spectra, and identifying the wavenumber of the major peaks in the spectra. You will also learn basic liquid cell techniques and the use of the new (February 2004) diamond ATR attachment.Tasks for Week of March 3/4 (Teams A & C from 2 - 3:20; Teams B & D from 3:30 - 4:50)(Teams E & F. #3-9, from 2 - 3:20; Team G from 3:30 - 4:50)1. Receive class/group instruction on the use of the P.E. 1600 FTIR spectrometer and software.2. Produce, save, and print a FTIR spectra of natural gas. (Team project with help of lab assistant)3. Receive group instruction on the proper handling, filling, and cleaning of a NaCl liquid cell.4. Prepare, save, and print a FTIR spectra of "toluene" which includes the wavenumber of the major peaks.5. Prepare a background scan and print a spectra for our collection of pre-mounted thin film plastics. Include wavenumbers for the major peaks. Each person should do at least one film.Save the thin film FTIR spectra to a floppy or Zip disk.6. Give originals of all printed spectra to Jumpol or JVF for copying. If time is available, the Aset@ will be handed out today. If not, then the set will be available next Tuesday in class.Tasks for Week of March 10/11 Team times are reversed for both days (e.g. A&C come at 3:30). 7. Bring your copy of the "set" of FTIR spectra produced last week.8. Produce a FTIR spectra of a wrapper material you have found that is made with "post industrial" or "post consumer" plastics (magazines typicallyuse such a wrapper).9. Produce a FTIR spectra of an "unknown" (same unknown # as assigned in class) piece of thin plastic film (provided by us), print the spectra with the wavenumber of the major peaks. You should be able to identify the "unknown" material using interpretation tables OR based on a comparison with the "standard" spectra produced previously (#5 above). We also have some reference spectra of plastics in a notebook available in the lab.10. After all the plastics have been run, we will install the new diamond ATR sample attachment. We will also provide a set of liquid compounds that illustrate common functional groups. From the set, select at least four knowns for spectral determination on the ATR. Produce the scan, save the FTIR spectra to disk, and print the spectra with wavenumbers of major absorbing peaks marked. Give your properly labeled spectra to Jumpolor JVF, who will copy them and give each of you a set TODAY.11. Using the ATR, prepare an FTIR spectra of an organic unknown with your assigned unknown number. Save the spectra to disk and print it for your personal use.FTIR Lab page 2REPORT (Due March 23, 2004)Your MEMO report for this set of lab activities should be brief but include the following:1. Interpret the FTIR spectra of natural gas (# 2 above). What can you conclude about determining the gaseous mixture=s Apurity@ by FTIR?2. Identify (e.g. C-H stretch) at least four of the major peaks in each of the thin film FTIR spectra (reference #5 above).3. Identify the polymer or co-polymer used to make each of the thin films used in # 5 above by name and chemical structure.4. Interpret and then compare the spectra for "toluene" to a literature FTIR spectra for toluene. Be sure to identify the source of the literature/referencetoluene spectra and to include a copy of it. What do you conclude about thequality of the literature spectra compared to your spectra? What do you conclude about the purity of the laboratory "toluene?@5. Based on the FTIR spectra of the wrapper made from post industrial/consumer materials (#8 above), what polymers do you believe thewrapper was made from? Justify your conclusion.6. Interpret the FTIR spectra of your unknown thin plastic film (#9 above) and suggest a polymer or co-polymer it is made from (e.g. polystyrene). Explain your conclusion.REVISED:7. Interpret the FTIR spectra (i.e. identify at least the functional group absorbances/peaks) of your group=s liquid and/or solid knowns (# 10 above) run using the diamond ATR. If you run your liquid unknown (#11), which was made optional due to potential odors, try to identify your unknown or at least what compound it isAsimilar@ to. ASimilar to@ should include the primary functional group in your liquid unknown..UNKNOWN THIN FILM PLASTICS: ChFE 5503, FTIR Lab. Spring, 20041. Chem. Eng. Progress (CEP) Journal Wrapper2.
