1 st ANFEC Training Workshop on Environmental Contaminant

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

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

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 -

Instrument �There are 3 main parts of SMS 100 § Auto sampler § Oven § Detector

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.

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

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.

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