tomic absorption spectrometry at 254 nm with Zeeman correction for background absorption for interference-free measurement.
APPLICATIONS
Direct determination of the mercury concentration in solid and liquid samples, such as:
foodstuff and biological materials;
crude oil and naphtha;
coal, fly ash, gypsum;
USEPA 30B, PS12B and CEN/TS 17286 sorbent traps;
passive air samplers;
waste waters and sludge;
soils and sediments.
PRINCIPLE OF OPERATION
Direct thermal decomposition of a sample and subsequent measuring the absorption of the 254-nm resonance radiation by mercury atoms using Zeeman correction for background absorption.
FEATURES AND BENEFITS
Direct mercury determination in samples with complex matrices
Highest selectivity
No pre-treatment procedures required
Broad dynamic measurement range: > 5 orders of magnitude
Automated temperature adjustment control for dynamic range enlargement
No memory effect
Thermoscanning option
Visualization of mercury output from the sample, user-friendly computer interface
High calibration stability
No carrier gas is needed
