  1. 1st ANFEC Training Workshop on Environmental Contaminant Analysis 18-20 December 2012at Royal University of Phnom Penh Organized by: Asian Network of Research on Food and Environment Contaminants (ANFEC) Supported by: - Royal University of Phnom Penh, Cambodia -International Science Programme, Uppsala University, Sweden.

  2. SMS 100 MERCURY ANALYZER Using the principle of thermal decomposition, amalgamation and atomic absorption. The SMS 100 is a stand alone mercury analyzer for the determination of total mercury in solid and liquid samples.

  3. The SMS 100 • Uses a decomposition furnace to release mercury vapor • No chemical reduction step • Both solid and liquid matrices can be loaded onto the instrument’s auto sampler • Analyzed without acid digestion or sample preparation

  4. Instrument • There are 3 main parts of SMS 100 • Auto sampler • Oven • Detector

  5. Auto sampler • Its 70-positions auto sampler allows to load sample “on the fly”, so one rack of samples can be analyzed while the next is being loaded.

  6. Oven • The sample is heated in an oxygen rich furnace • The products are than carried to a catalyst section • Only the mercury is trapped on an amalgamation cell • The amalgamation cell is heated and release mercury vapor

  7. Detector • Spectrophotometer • Mercury Lamp • Absorbance is measured at 253.7 nm Flowing Oxygen carries the mercury vapor thought an absorbance cell positioned in the light path of a single wavelength atomic absorbance spectrophotometer.

  8. BENEFITS • No sample preparation • Extremely low detection limits • Full automation for maximum productivity • Reduction in analysis time
