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.
PRINCIPLE OF OPERATION
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.
FEATURES AND BENEFITS
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
APPLICATIONS
