Report To Organic Chemists Μ/ΔΜ=50,000 with new CEC Type 21-110C Mass Spectrometer. CEC guarantees a resolving power of 5 0 , 0 0 0 (50% valley) for the newest model of the 110 series of double-focusing mass spectrometers. As a result, organic chemists can now realize extended capability for molecular determination studies. For the 21-11ÛC permits separation of ions at a higher mass range and increases sensitivity at intermediate resolving power. Look w h a t Μ / Δ Μ = 5 0 , 0 0 0 can do for you: REQUIRED R E S O L V I N G POWER OF S O M E C O M M O N DOUBLETS
Oscillograph trace from the Peak Matching System that Is standard with the 21-110C. Sample is the mass 78 doublet of a benzene/ monodeuterobemene mixture. Resolving power in excess of 50,000.
In addition —the 21-110C also offers the ad vantages of unexcelled electrical and photoplate detection capabilities. For complete information, w r i t e Consolidated Electrodynamics, Pasadena, California 91109. A subsidiary of Bell & Howell. Ask for Bulletin Kit 1735-X1.
