  1. 2537A Tekran Mercury Analyzer Overview

  2. Tekran Model 2537A Analyzer

  3. Model 2537A Mercury Analyzer • Provides continuous TGM readings with update rate as low as 2.5 minutes • Detection limit < 0.1 ng/m3( 12 ppq ) • Automatic recalibration with internal permeation source • Capable of unattended operation for extended periods • Data can be viewed remotely

  4. Flow Diagram of Model 2537A

  5. Pure Gold Cartridge (Pat’d)

  6. Manual Mercury Sampling • Traditional methods of atmospheric monitoring required manual sampling for long periods. (Hours or days) • Subsequent analysis usually performed in a clean room environment

  7. Manual Ambient Air Sampling

  8. Manual Cartridge Analysis

  9. Chlor-alkali Plant - USA • Plot of wind vs ambient mercury values • Two months of continuous monitoring • Plant is located 18 miles distant • Fish consumption advisories in effect

  10. Depletions of Mercury in the Arctic

  11. Mercury Monitoring in the Field • Tekran analyzers are used routinely in some of the harshest locations on earth. • The equipment has demonstrated its ruggedness and reliability in countless applications.

  12. Why Measure Parts Per Quadrillion of Mercury ? • Mercury is one of the most potent neuro-toxins known • Bio-accumulates up the food chain by factors of greater than 10,000,000 • Long life in the atmosphere means that mercury emissions are of global concern

  13. Sources of Mercury • Mining & smelting (gold) • Waste incinerators • Battery manufacturing • Fluorescent lamps (manufacturing & disposal) • Chlor-alkali plants (pulp & paper) • Coal fired power plants
