The Polarecord E 261-R is t h e only i n s t r u m e n t currently available which can be applied to the various polarographic m e t h o d s now developed because it provides t h e chart-speeds, voltage scan speeds, mechanical systems, and c o m p e n s a t i o n facilities necessary for effective use of these procedures. The e q u i p m e n t illust r a t e d is all t h a t is required for N o r m a l , Rapid or Stripping Analysis Polarography—and permits the d e t e r m i n a t i o n of con-

centrations t o 10- 9 Molar. For A. C. Polarography, an auxiliary power supply is offered. Recently, new analytical procedures based on the use of our exclusive controlled ( r a p i d ) forced d r o p p i n g m e r c u r y electrode have been developed by m a j o r U.S. chemical laboratories using t h e Polarecord.
