Liquids analyzer RA-915F

mercurysolidsmonitoring

RA-915F is a streamlined benchtop mercury analyzer designed for fast direct analysis of all kinds of solid, liquid, and biological samples, starting from ppb level. Operating this instrument does not require the use of reagents nor compressed gases. The compact design also makes RA-915F ideal for mobile laboratories. 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 exploitation complexity No memory effect: a sample with low mercury concentration can be analyzed immediately after a high mercury sample
