*Polarograph is the registered trade-mark of E. H. Sargent
& Co. for electrical analyzing apparatus. No other manufac-
turer may use the name "Polarograph" for electrical analyzing
apparatus, nor should the name "Polarograph" be used by any-
one except when referring to E. H. Sargent & Co. apparatus.Principal reasons for the steadily ex-
panding use of the Heyrovsky
Polarograph are-
* Accuracy
* Rapidity
* Sensitivity
* Simultaneous determination of
several components
* Detecting and identifying minute
quantities
* Small sample requirements
* Preservation of sample
* Permanent photographic record-
ing of each analysis
* Elimination of subjective errors
Versatility and directness of analysis
with the Heyrovsky Polarograph
have resulted in the development of
innumerable new methods in almost
every field of research.
Typical application of polarography are
the analysis of-
Petroleum
Brass
Aluminum
Zinc and die cast metals
Rubber
Food
Beverages
Heavy chemicals
Dyes
Drugs
Pharmaceuticals
Ferrous metals
Explosives
Paint and varnishes
Organic chemicals
Plastics
and wherever polarographically reducible
constituents are encountered.E. H. SARGENT & COMPANY, 155-165 East Superior St., Chicago 11, Illinois
