The Perkin-Elmer Model 180 Infrared Spectrophotometer. Designed for the world's most demanding spectroscopist.
Here is an instrument with the widest research versatility of any IR instrument ever offered. Its unique capabilities give you unrestricted selection of instrumental parameters. You have total freedom to set the precise combination of resolution, speed, time constant and gain that you need. Its large sample space—with unequalled accessibility from front, back and floor—permits you to place almost any configuration of sampling accessory into the instrument; and its chopping system even lets you run very hot or cold samples without loss of transmittance accuracy.
You can operate in either a single beam or a double beam mode—either way with full system energy. And you have total flexibility in the choice of energy mode —choose constant l 0 , or programmed or manual slit control, with or without automatic gain. The dual recorder gives you eitheran XY or a strip chart recording. And you have exceptionally wide control of spectrum presentation. A digital indexing system lets you quickly set the scan limits, and you have continuous visual display of frequency while scanning. The Model 180 has excellent data logging capability in which
data are presented in ASCII code for interface with data loggers through the standard Perkin-Elmer interface option. An accessory Digital Magnetic Recorder permits recording of high resolution spectra at rates 5 to 100 times faster than is possible on the chart. If you require the ultimate in flexibility, precision and operator convenience in your IR instrument, you owe it to yourself to investigate the Model 180.
