DC Stripping Voltammetry
Adsorptive Stripping Voltammetry
Differential Pulse Polarography
Cyclic Voltammetry

The sensitivity of the instrument is comparable with AAS and in many cases it is even better.

The example above shows the simultaneous determination of Zn , Cd, Pb and Cu using standard addition


Applications Determination of trace elements Pb, Cd, Cu, Fe, Ni, Co, Al, Cr, Hg .... Determination of nitrate, nitrite, chloride, iodiide, cyanide, oxygen ..... Determination of numerous organic and toxic materials - surfactants, herbicides, pesticides, insecticides, nitro compounds, halogenous compounds .... Tribodiagnostics of oils and lubricants The GAT 4000 polarography / voltammetry system is suitable for use in the laboratory or on site in many fields of application including: water analysis of natural, waste and fresh water; food and beverage, sanitation, environmental analysis, pharmaceutical, chemical, oil and plating industries, medicine, biology, geology and tribometry. The instrumentation is supplied with a comprehensive manual of analytical methods.

Electrodes A selection of electrodes are available to meet the needs of your application including special applications electrodes: Gold Electrodes for the determination of mercury, and arsenic and for the use of an Hg film HMDE Hanging mercury drop electrode with a minimum of < 1.5 mL/ year of Hg consumption. Glassy carbon electrode for the use of Hg film ( MFE ).
