1. 1 st ANFEC Training Workshop on Environmental Contaminant Analysis 18-20 December 2012 at 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
