quick, accurate gas analyses with low-cost, easy - to - operate,
analytical m a s s s p e c t r o m e t e r available for batch or continuous analysis This easy-to-opcrate analytical instrument provides high sensitivity at low cost . . . with unusual portability that enables industrial engineers and research scientists to improve quality control and analytical service in plant, laboratory, or field applications. The 21-611 features rugged, modular construction . . . weighs only 1 15 pounds. Easy to install in a trailer, on a bench,or in a plant, where its separate vacuum module may be stacked with or operated apart from its electronic module. Highly dependable and stable, the 21-611 operates with exceptional reproducibility in the mass range from 2 to 80 with resolving power adequate for separation of adjacent peaks up to mass 32. A unique scanning dial eliminates mass marking.
and a new, metal rotary valve makes batch sample introduction a routine operation —even for inexperienced personnel. The 21-611 analyzes individual samples as small as 0.1 standard cc of gas or 0.001 cc of liquid. Complete analysis takes less than a half hour, while measurement of single components can be made in a matter of minutes. As a process monitor in the plant proper, the 21-611 samples directly from the process stream or atmosphere. It instantly rctlects deviations from optimum operation, provides analyses that improve process control and result in better product quality and yield. For complete information, call your nearby CEC sales and service office, or write for Bulletin CEC I843A-X13.
