The advanced mercury analyzer RA-915+ is a unique all-purpose high sensitivity analytical instrument for the environmental monitoring, especially for the real time detection of mercury vapor in air, mercury detection in water, natural and stack gases, oil and condensate, solid and sediments, foodstuff and so on. MEASUREMENT PRINCIPLE RA-915+ is an atomic absorption spectrometer, which employs the effect of the resonance radiation absorption by the mercury atoms. - Proprietary scheme of the Zeeman correction for non-selective absorption provides high measurement accuracy irrespective of interfering factors, such as dust, aerosols, absorbing gases and vapors.
- Multipath cell with an effective optical length of 10 m provides the highest measurement sensitivity.
RA-915+ ADVANTAGES
2 ng/m3 Hg in the AIR ! - Ultra low detection limit
- High selectivity of analysis
- Direct continuous mercury detection (without preliminary mercury concentration on a sorbent)
- Capability of operation in the field using a built-in battery
- User-friendly computer interface
- Background monitoring of mercury vapor
- Direct analysis of complex gas mixtures
- On-line measurements
- Wide dynamic range of the direct measurements:
2 – 50 000 ng/m3 - with a multi-path cell
5 000 – 200 000 ng/m3 - with a single-path cell - Measurements from moving objects
