w i t h B e c k m a n IR-5 and IR-6 Infrared Spectrophotometers The unique identifying characteristics of many com pounds—especially the organics—are best fingerprinted by infrared analysis. From the more than 1,000,000 known chemical compounds, thousands of infrared spectra have already been obtained and cataloged for ready reference. Backed with this reference library, Beckman's new low-cost automatic recording spectro photometers—the double-beam IR-5 and the single-beam IR-6—now bring infrared to the chemist's bench.
Beckman—producer of the versatile and popular IR-4 —offers the IR-5 and IR-6 at one-third of big instrument prices. Emphasizing simplicity of operation, these new instruments maintain Beckman's high standards in accuracy, reliability, and reproducibility. For rapid qualitative or quantitative analysis in re search, education, or industry—the IR-5 and IR-6 are new tools for the chemist, extending his use of spectro scopy beyond the range of ultraviolet and visible light.
IMPORTANT FEATURES
THE DOUBLE-BEAM IR-S. F o r rapid qualitative scanning. Accurate quantitative d a t a made possible through use of a densitometer. THE SINGLE-BEAM IR-6. Especially useful in routine quantitative analysis. Application to qualitative work is enhanced by compensated background feature. For typical IR-5 and IR-6 applications and a more complete story on infrared analysis, write for Data File BL-39-lô.
