The IR-102 can...almost as last as you can say, "Beckman IR-102 infrared Spectrophotometer." Peak 2 is isopropyl acetate. And the Beckman IR-102 Infrared Spectrophotometer made the identifying infrared scan of this peak in just five seconds, taking the 0.6 microliter sample directly from a chromatographic column. It can also give you the infrared spectra of each of the other peaks at the same rate. Five seconds is all it takes to scan from 2.5 to 14.5 microns when your chromatograph is connected to the IR-102 Spectrophotometer.

The IR-102 was primarily designed for use with gas chromatographs. It allows you to identify components as they come from your gas chromatographic column, even with fast eluting samples. It eliminates trapping, transferring, and condensing problems because it handles samples in the same

state as a chromatograph — as a hot vapor. Its high sensitivity allows analysis with fractional microliter volumes and submilligram quantities. And, the IR-102 is adaptable to any gas chromatograph.

In addition to identifying complex mixtures by rapid scan infrared, the IR-102 can be used to complement the gas chromatograph as a specific detector. It can monitor fractions at a fixed wavelength, giving data on specific functional groups or on isomers that cannot be separated chromatographically.

Total analysis of unknown mixtures is no longer a problem; your gas chromatograph and the IR-102 are a natural team. Whether you already have a chromatograph or are about to

get one, this instrument is a must for your laboratory.

For more information on the IR-102, write for Data File IR-166. Or contact your local Beckman Sales Engineer. He'll be glad to show you how to make an infrared scan almost as fast as you can say, "Beckman IR-102 Infrared Spectrophotometer." The IR-102 employs a circular variable interference filter developed and manufactured to Beckman specifications by Optical Coating Laboratory, Inc., of Santa Rosa, California,
