Product Details

The Australian MTI PDV6000plus portable heavy metal analyzer is a classic product designed using voltammetry. It has excellent performance, high cost-effectiveness, and a user-friendly interface. Its operation is simple and the design is convenient.

Brief description of heavy metal determination method for Australian MTI PDV6000plus:
MTI's OVA/PDV series heavy metal detection products have been in use worldwide for nearly 20 years and have always been the highest market share products in the world. Their products have received strict testing and recognition from the US Environmental Protection Agency.
The MTI heavy metal detection equipment adopts the principle of voltammetry (i.e. anodic stripping method): this method involves enriching the analyte on the electrode at a constant potential (i.e. the potential equivalent to the maximum current generated on the cathode of the heavy metal ion to be tested), and then moving the potential of the microelectrode from negative to positive. During this process, the enriched substance is dissolved in the opposite direction (anodic stripping), and the concentration of heavy metal ions can be accurately determined through the voltammetry curve.
Voltammetry (anodic stripping method) has been widely used in pharmaceutical, biological, and environmental analysis in the United States, replacing traditional atomic absorption methods due to its low cost and high sensitivity.
Authoritative agencies such as the US EPA have also listed it as a standard testing method, such as EPA7063, 7472, 1001, and so on.

Australian MTI PDV6000plus portable heavy metal analyzer product features:

high-precision:	The detection accuracy can reach 1ppb~6ppm (the actual detection limit can be lower);
Quick detection:	The detection time only takes a few tens of seconds, and the preparation time before detection only takes a few minutes;
Detection spectrum width:	The PDV heavy metal analyzer can detect the concentrations of more than 20 metal ions, including cadmium, copper, arsenic, mercury, lead, zinc, antimony, thallium, chromium, manganese, etc., through software settings. Only some detectable metals are listed here, which can also be used for a wider range of metal detection;
Strong anti-interference ability:	Not detecting first and second class metals such as sodium, potassium, etc., eliminates the influence of interference factors such as sodium chloride;
Support self-developed detection methods:	In addition to the 20 ion detection methods currently provided by manufacturers, the detection capability of the equipment itself can detect dozens of ions, and users can still develop more detection methods according to their own needs;
Low cost of use:	Low startup cost, minimal consumption of consumables, and low operational workload; If the laboratory conditions are good, some consumables can be prepared by oneself.
Easy to use:	Lightweight, compact in size, and easy to carry. It can be used for laboratory testing as well as field testing.
laboratory:	Connect to a computer for use. Equipped with dedicated software to support programmable analysis menu control of the detection process, resulting in higher detection accuracy.
Field site:	Rechargeable batteries ensure power supply, and detection data is directly displayed on the LCD screen;
Security guarantee:	The design of the reaction box is reasonable, and personnel can avoid contact with toxic substances such as mercury when using it;
Liquid detection:	The operation is very convenient, and currently PDV is widely used in fields such as drinking water purification, drinking water sources, surface water, beverages, and environmental water monitoring.
Solid state detection:	It is necessary to extract heavy metal ions from the sample to be tested first, which takes about 10 minutes. At present, PDV is widely used for the determination of heavy metal content in solid substances such as soil, food, and solid waste.
The parameters of voltammetry are fully controllable:	The VAS software allows users to control all the voltammetry parameters in the experiment, and setting these parameters can obtain the best analysis conditions.
The main features of VAS software are:	Multiple metals can be detected in a single operation Deducting blanks can reduce the impact of interference Both quantitative analysis using standard comparison method and analysis using standard addition method will display curve graphs The detection limit can be increased by adjusting the smoothness and averaging of the data Overlapping peaks can be identified by adjusting the detection of peak centers You can upload any upgrade kit released by the manufacturer to the PDV6000plus unit The editable program enables analysis of different metal types up to 10 The editable program can adjust up to 10 working electrode menus The data will be automatically saved and labeled with time and date after each operation Generate reports and provide complete color charts
