Control Analyzer

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
