Measuring trace metals in water, soil and food has always been a vital part of modern environmental monitoring. Voltammetry offers an internationally accepted alternative to laboratory analysis. Modern Water’s PDV provides better on-site characterisation, with pollution hot spots and contamination sources more easily identified.

Modern Water’s tried and tested metal monitors have been market leaders for over twenty years. They provide an convenient way to generate and store real-time data, which allows real-time decision-making. Our PDV6000ultra can be more cost-effective than laboratory analysis and it can be used “stand-alone” or on a computer with our powerful VAS software.
 

Description
The PDV6000ultra has been upgraded to allow much improved stand-alone operation and an indication of blank and standard run performance. A larger screen allows simple voltammograms to be shown. The USB connector replaces the serial por t. The upgraded product has a battery life indicator and can be run either on 4 x 1.5V AA batteries, or from the mains using the standard 8 - 12V DC transformer.

The PDV6000ultra comes with the VAS software package, which is easy to use and is compatible with Windows XP and 7. VAS enables storage and manipulation of voltammograms, operating data and in-depth data analysis.
The SV LabCell
Our PDV6000ultra comes equipped with a standard analytical cell which can detect a wide range of different metals. The SV LabCell is an optional extra that allows Cathodic Stripping Voltammetry (CSV) to be used on the PDV.

The SV LabCell extends the PDV’s range of metals to include molybdenum and uranium; it also gives a better response for nickel, cobalt and chromium at low levels.

 

Features
  • Multiple, sequential metal analysis when using VAS
  • AC or rechargeable battery for onsite use
  • Solid-state robust electrodes and stand provided
  • Detection limits below 1ppb, depending on sample
  • Report generation capability using VAS software.

 

Applications
  • Academic research
  • Monitoring at remote locations
  • Contaminated land remediation
  • Food and feed analysis
  • Tracing contamination back to source
  • Accidental contamination events
  • Monitoring of rivers, lakes, reservoirs, seawater
  • Industrial effluent monitoring
  • Groundwater monitoring / natural attenuation
  • Wastewater recycling and WWTP influent monitoring
  • Drinking water intake and distribution

 

What it detects
The PDV6000ultra can detect a range of different metals (for example As, Cd, Cr, Cu, Hg, Ni, Pb, Se, Tl, Zn, and others. Please refer to Trace Metals brochure for a full list of metals and their detection limits) to single figure ppb levels. With the optional add-on SV LabCell, the PDV6000ultra can detect Co, Cr and Ni more easily, typically to 1ppb levels. The SV LabCell can also detect Mo and U. Colour or turbidity does not affect the method. Ideally suited for water analysis, dirty water samples and soil samples may require simple on-site sample preparations to remove interferences. Food samples will require digestion to prepare them for analysis. Samples can be pre-treated to remove interferences.

 

Process explained
In voltammetry metals are drawn onto the working electrode when a specific voltage is applied to the water sample under test.

When a stripping voltage is applied, the metals return to the sample solution, generating a small current. Each metal has a specific voltage at which it returns to solution. So the metal is identified by its stripping voltage, and the current generated indicates the concentration of metal in the sample.
