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.
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 low detection limits • Full automation for maximum productivity • Reduction in analysis time
