Now you can improve your process control or analytical service with an inexpensive, portable mass spectrometer. CEC's completely new 21-611 adapts easily to installation in a trailer, on a bench — wherever there is space for the 115-lb unit. The instrument covers mass range 2 through 80, with automatic scanning from mass 12 to 40 requiring only 3 minutes. Extremely rugged and simple to operate, the 21-611 consists of separate electronic and vacuum modules which may be operated stacked or apart. Ingenious design for trouble-free operation has eliminated the conventional cold trap, one forepump, magnet shunt, and several vacuum tubes. Investigate this outstanding value by calling your nearby CEC field office, or write for Bulletin CEC 1843-X3. Capable of analyzing minute samples of gases, gaseous mixtures, or vaporized liquids with precise accuracy, the economical 21-611 offers automatic programming of control mechanisms and a unique scanning dial which eliminates mass marking Complicated sample introduction procedures are unnecessary with the simplified batch inlet system featuring a single all-metalrotary valve. Entire portable unit weighs only 115 pounds.
