Portable Zeeman mercury analyzer RA-915+ with RP-91C attachment |
|
 |
|
|
|
RA-915+ mercury analyzer with RP-91C attachment is used for determination of mercury concentration in solid samples (soil, rocks, sediments, etc.).
RP-91C attachment is intended for thermal decomposition of a sample and transferring of bound Hg from ion to atomic form and further determination of atomic Hg using RA-915+ analyzer.
Analytical characteristics
| Subject | Detection limit, µg/kg | Sampling, g | | Solid samples (solids, rocks) | 1 | 0.4 |
Measurement procedure
Put the sample (from 20 to 300 mg) to the sample boat. Switch on integration of the analytical cell and insert the sample boat into RP-91C attachment. Integration will be finished in 60-120 sec when the analytical signal goes back to the baseline. | principle of operation | | |
| Is based on the absorption of the 254-nm resonance radiation by mercury atoms using Zeeman correction for background absorption.
| features and benefits | | |
| - Express Hg content determination in soil, rocks, sediments and samples with low content of organic substances by pyrolysis technique;
- High selectivity of analysis;
- Wide dynamic range;
- User-friendly interface;
- Visualization of the process of Hg coming from the sample;
- Automatic control of level of non-selective absorption.
| areas of application | | |
| RA-915+ mercury analyzer with RP-91C attachment can be used in ecology, sanitary, and geological and geochemical survey. Rapid-analysis of complex objects: - raw materials and industrial products;
- ecological-geochemical samples
