RA-915F offers accurate, reliable, and cost-effective Hg measurements through direct thermal decomposition in the broadest range of applications. With RA-915F, even complex-matrix samples are analyzed ‘as is’ without the need of pre-treatment.
Direct thermal decomposition followed by atomic absorption spectrometry at 254 nm wavelength with Zeeman correction for background absorption makes interference-free measurements easy and quick. It provides the most selective and sensitive analysis without matrix effects.
- Fast direct analysis of solids, liquids, and biosamples
- Low limit of detection and highest selectivity due to Zeeman background correction
- The unique real-time feedback system for sample decomposition control extends the dynamic range and eliminates background interferences
- Broad measurement range: more than 5 orders of magnitude
- No need for sample pretreatment and reagents reduces analysis cost
- Safe and simple running: no compressed gases (oxygen or argon), air is used as a carrier gas
- No pre-concentration on gold traps increases analysis speed and reduces operational complexity
- No memory effect: a sample with low mercury concentration can be analyzed immediately after a high mercury concentration
- Programmable furnace for optimal sample decomposition and mercury thermospeciation study
- Compact size: possibility to use in mobile laboratory
RA-915F mercury analyzer is used for the direct determination of mercury concentration in:
- soils, sediments;
- food, nutritional additives, animal feedstuff;
- crude oil, oil products, naphtha, petrochemicals;
- biosamples: tissues, hair, urine, blood, etc.;
- waste waters, wastes, sludge;
- coal, coke, fly ash, gypsum;
- rocks, ores, minerals;
- sorbent traps for stack gases;
- drugs and cosmetics;
- plastics, fertilizers, and many other materialspassive air samplers;
- passive air samplers.
Direct thermal decomposition technique meets national and globally accepted standards such as ASTM D6722, D7622, EN/TS 17286, US EPA 7473, 30B, PS12B, SN/T 4429.2-2016, HJ 923-2017, and others.
RAPID is an efficient and intuitive software designed for the operation of RA-915 Lab mercury analyzer. RAPID software fully complies with FDA 21 CFR Part 11 requirements.
It provides:
- data acquisition, processing, and reporting;
- real-time visualization of selective and non-selective absorbance;
- databases for calibrations, processing and storage of measurement data;
- adjustable modes for optimal thermal decomposition of any specific matrices.
Automatic closed-loop temperature control extends the measurement range and ensures no data loss during analysis of complex-matrix samples or highly contaminated samples.
RA-915F mercury analyzer is covered by a full 1-year warranty.
Upon request installation and commissioning of RA-915F mercury analyzers can be carried out at customer’s site by our service engineers or by certified distributor. Support and training of operators, meeting customer’s specific needs, are provided by highly qualified application specialists.
