G-E X - R A Y PHOTOMETER For a n a l y z i n g s o l i d s , l i q u i d s , o r g a s e s This instrument, used to determine the concentra tion of one element or compound in the presence of others, speeds up routine tests required in process control. For example, a technician can quickly determine the fetraethyl lead content of gasoline, or the chlorine and sulphur content of oils. Write for GEC-412.
Installation of the G-E X - r a y photometer is simple.
G-E MASS SPECTROMETER For chemical analysis b y mass s e p a r a t i o n The improved G-E mass spectrometer automatically and accurately records mass concentrations over the mass range of 1 to 330. Readings are direct. I t is w e l l suited for: routine process control study of reaction rates research using isotopes detection of impurities W r i t e for G E C - 5 8 7 .
G-E ULTRASONIC GENERATOR For industrial r e s e a r c h in ultrasonics T o help you carry on industrial research, G.E. offers a new ultrasonic generator for:
G-E mass spectrometer g i v e s direct readings—no w a i t i n g for photo graphs.
Studying o x i d a t i o n , hydrolysis, and reduction Transforming immiscible liquids into stable e m u l sions
{
G-E ultrasonic generator is simple to operate.
Some plants, for example, are studying the use of ultrasonics to degrease products and to develop im proved fuels. Write for GEC-5 44. G-E D E W P O I N T RECORDER . . . f o r d e t e r m i n i n g t h e moisture c o n t e n t of gases The dewpoint recorder, which records the moisture content of gases, helps you to maintain close quality control of factory processes, thereby reducing spoilage. For example, you can use the recorder to control mechanical or chemical dryers, and furnace atmos pheres. Write for GEA-4613. Apparatus Dept., General Electric Company, Schenectady, Ν. Υ.
