Perkin Elmer PE 1600 FTIR

The Perkin Elmer PE 1600 FTIR is a standalone FT-IR with built in microprocessor, keyboard and CRT display, but can be configured with PC and data station and PE Spectrum Windows Software. These instruments are very very sturdy, reliable and easy to operate....and affordable

Typical Operation for obtaining an IR spectrum with the Perkin Elmer PE 1600 FTIR without the computer and (recommended) software to aid in data analysis and data archiving:

1. The instrument is left on all the time--it is not necessary to turn it on.
2. Make sure the sample compartment is empty. BE CAREFUL--laser radiation. Don't look directly into the laser beam.
3. Turn up the monitor brightness with the control located behind the monitor. You should see "Press Enter to Continue" scrolling up the screen.
4. Press Enter on the PE keyboard. This gives the "Ready for Next Command Screen." You should see the words "Ready" and "Survey" (in orange) in the lower right corner of the monitor.
5. Run a baseline spectrum. This involves choosing the number of scans to be carried out. 1 is a good choice for routine samples.
   1. Press Backg (a grey key in the center group of 12 keys).
   2. Press Scan (a green key near the bottom of the keyboard).
   3. Select the number of scans (usually 1) by pressing the appropriate key in the row of keys directly under the monitor. Each of these keys corresponds to the number of scans shown directly above it on the monitor. When you press one of these keys, scanning of the background begins immediately.
      The selected number of scans remains in effect until it is changed using the procedure above.
      The background spectrum will be dispayed on the screen shortly after the scans begin and will remain for a short time on the monitor after completion of the selected number of scans, then will disappear. If desired, you may view it by pressing Backg.
6. Obtain the sample spectrum
   1. Place sample in instrument sample compartment.
   2. Press Scan (green key)
   3. Press the right most key in the row of grey keys below the monitor, under the word "Execute".
      The spectrum will be acquired, using the # of scans selected in 5-3.
   4. Rescale the spectrum. Press Rescale while holding down the white shift key at the bottom left corner of the keyboard.
   5. Flat the spectrum.
      1. Press the Flat key (column of grey keys at right side of keyboard).
      2. Select "Auto" using the row of keys under the monitor. This will carry out an automatic baseline flattening routine.
      3. Further corrections can be carried out using the "More" or "Less" options, activated using the appropriate keys in the row under the monitor.
      4. When you are happy with the result, select "Execute" to save the changes.
         Note: If you don't like the results of the automatic or manual flattening, you can cancel all changes by pressing the red Cancel key at the top of the keyboard. This must be done before selecting "Execute".
   6. Scale the spectrum. Press Shift Autex.
      This places the spectrum to maximum advantage on the screen.
7. Plot the Spectrum
   1. Turn on the plotter using the upper left key on the plotter keyboard.
   2. Load a piece of paper. Slide the paper in the front until the leading edge of the paper aligns with the white mark on the plotter deck. Then press the white key just below the On/Off key on the plotter keyboard.
   3. Press the green Plot key on the FTIR keyboard. The spectrum will be plotted just as it is displayed on the monitor screen.
   4. Eject the paper by again pressing the white key below the power key on the plotter keyboard.
8. Remove sample from instrument sample compartment.
9. To obtain further spectra, repeat steps 6, 7, 8.
