The Polarographic Analyzer Model 4330/P combines two instruments for electrochemical trace analysis of heavy metals in organic compounds. Thank to the electronic evolution AMEL have combines both voltammetric and polarographic techniques with Potentiometric ones (PSA Potentiometric stripping analysis). In this way it is now possoible to select the most appropriate technique to carry out the analysis. With Model 4330/P you may perform analysis of heavy metals in organic compounds at μg/l. level. The instrument is supplied with Windows software.


Model 4330/P is the historical polarograph by AMEL, developed to be used with the built-in mercury valve that can be operated both as Hanging Drop Mercury Electrode or Dropping Mercury Electrode. Thanks to the constantly updated circuitry, detection limits can be pushed below the ppb level.
