The
Beckman INFRARED
Spectrophotometer τ H E Beckman Infrared Spectrophotometer is the most advanced development in hydro carbon gas analysis and control—vitally important operations in today's war-paced synthetic rubber and aviation gasoline pro grams. This instrument was developed in one of the nation's leading petroleum labo ratories and has been perfected and thor oughly proved t h r o u g h more t h a n two years9 use in actual refinery control. It is not experimental! M a n y . T i m e s F a s t e r T h a n O t h e r JVletfriocSsJ Readily Analyzes Complex

r \ The instrument analyzes hydrocarbon gases b y *Ύ measuring the absorption of infrared radiation a t selected wave lengths. Since every hydrocarbon has its individual a n d characteristic infrared absorption pattern—analogous to a finger print—each component in a mixture is unerringly identified a n d its concentra tion accurately determined—even in complex hydro carbon mixtures. r \ The procedures are simple. The instrument is espenr d a i l y designed f o r fast a n d fool-proof routine operation a n d accurate analyses can b e made b y rela tively unskilled operators. -*· r \ The instrument is easily pre-set f o r as m a n y as 1 8 n/ w a v e length positions, corresponding t o hydrocar bons o f specific interest, a n d needs only infrequent calibration checks. In routine operation these positions a r e instantly and precisely reproduced by a single i n dexing stop. No dials t o r e a d or adjustments to makel
THE JBECKM^N INFRARED SPECTROPHO TOMETER Is not only essential to the efficient operation of present-day aviation gasoline and synthetic rubber processes, but also makes pos sible entirely new advancements in the field of hydrocarbon research and development.
