Application – Mercury in Lichen / “Why Choose the MA-3000?”



  • Direct Mercury Analysis for results in Only 5 Minutes
  • Extended Dynamic Range Optics (Patent-pending) 0.001ng-2000ng linearity and cubic fit up to 70,000ng in a single calibration
  • Unique Dual-Cell Detector (Patent-pending)-Auto Range with Independent Detectors
  • 100 sample positions
  • Positive pressure sample container prevents contamination
  • Optional Attachments for Reducing Vaporization Method and Gas/Ambient Air Analysis
  • Tri-photo sensor optics (patent pending) design offers simultaneous low and high concentration range measurements, avoids cross over and co-elution of high and low peaks, which is inherent in other dual-cell detector design
  • Special moisture removal step helps to avoid catalyst overloading and saturation while extending the lifetime of catalyst tube
  • Ceramic sample boats allow for easy acid-washing and drying
  • Auto-blanking function on unexpected high level measurement to avoid carryover to next samples
