Description

LIQUID MERCURY ANALYZER RA-915M/RP92 RA-915M mercury analyzer with RP-92 attachment is used for determination of mercury concentration in liquid samples (water, blood, urine). RP-92 attachment is intended to transfer bound Hg from ion to atomic form using “cold vapor” technique. Measurement procedure Preliminary mineralization should be carried out by accepted procedure (ISO 5667, 7470, etc.). Add reduction solution into the bubbler. When integration is on after stabilization of an analytical signal, insert mineralized sample into the reaction vessel. Integration will be finished when the analytical signal goes back to the baseline. Results of analysis of a blank sample should be taken into account. 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 Any sample preparation technique can be used Ability to use single-path or multi-path analytical cell depending on the task (background measurement or analysis of highly contaminated waste water) Mercury determination without gold amalgam pre-concentration Wide dynamic measurement range more than 3 exponent (without sample dilution) Detection limit is on background level of mercury content in natural water Visualization of the process of Hg coming from the sample, user-friendly interface Calibration stability (it’s necessary to check the stability once a day) Possibility to carry out field analysis without a PC Measurement of low Hg concentration in drinking and natural water, foodstuffs Control of Hg content in wastewater and washouts Mercury determination in blood, urine and other liquid samples.
