Italian Amel 4330/P polarograph

Italian Amel 4330/P polarograph



Products: Polarograph

Model: 4330 /P

Brand: AEML

Origin: Italy


1. Product Introduction:

The AMEL 4330/P is a historic polarograph from AMEL that is used in conjunction with a built-in mercury valve and can be used as either a suspended or a dropping mercury electrode. Thanks to the constantly updated circuit, the detection limit can be reduced to below ppb. Polarography and voltammetry in one instrument.

AMEL 4330/P polarograph, test methods include amperometry (chronoamperometry), pulse amperometry, cyclic voltammetry, linear sweep voltammetry, conventional pulse voltammetry, differential pulse voltammetry, square wave voltammetry, Potential detection (chronopotential), alternating current voltammetry, constant current stripping analysis, potential stripping analysis, alternating current stripping voltammetry Differential conventional stripping voltammetry, linear sweep stripping voltammetry, square wave stripping voltammetry, etc.

The measured data is recorded by the control software, and the results can be calculated automatically. The software interface is clear, the operation is intuitive, the experimental parameters and the relevant voltammetric polarographic analysis chart are displayed on the same interface, and the background can be deducted through the software, and the linear or nonlinear curve can be found. The software can be used to differentiate, integrate, superposition, smooth and find special points on the measured curve.

3. Scope of application:

(1) Heavy metal analysis: The voltammetry analyzer can not only determine the total amount, but also determine the different valence states of metal ions or the type of heavy metal organic matter. Both free and bound metals can be analyzed. Voltammetry analyzer is an effective means of environmental analysis. Voltammetry analyzer does not have the problem of high concentration matrix interference, such as the analysis of high-purity chemical reagents and trace components in electroplating solution.

(2) Organic analysis: voltammetry analyzer can not only determine metal ions, but also can determine organic matter. For example, analysis of pollutants, analysis of active ingredients in pharmaceutical chemistry.

(3) Determination of anions: the voltammetric analyzer can also determine anions. For example, in the environment, cyanogen, sulfite, nitrite, nitric acid, etc.
