Environment, water and food
Trace-level heavy-metal determination and water and air monitoring — in the laboratory and in the field.
Controlling heavy metals in soil, water and food requires low detection limits and reliable calibration. Plasma techniques (ICP-MS, ICP-OES), atomic absorption (AAS) and atomic fluorescence (AFS) determine mercury, arsenic, lead and cadmium at ppb–ppt levels, in line with drinking-water and food-safety requirements.
For field and process monitoring, portable water and volatile organic compound (VOC) analyzers and online systems are available.
Recommended techniques and instruments
- ICP-MS, ICP-OES, AAS and AFS — trace-metal analysis, e.g. ICP-MS2000 and AFS200 for mercury, arsenic and selenium.
- Environmental and process analyzers — the portable water tester MW-3000P and the VOC-3000 analyzer.
- Determination of organic contaminants by GC-MS and LC-MS.
