Mercury-hydride generator GRG-112
Mercury-hydride generator GRG-112 It is used as an attachment to atomic absorption spectrometers KVANT.Z, KVANT.Z1 and is used to determine microimpurities of mercury. General characteristics of the generator and metrological characteristics The relative value of the systematic component of the error and standard deviations (RMS) of the results of measurements of mercury concentration when using a generator with atomic absorption spectrometers KVANT.Z, KVANT.Z1 should not exceed the values specified in table 1. Table 1 element Mercury concentration, µg/l RMS deviation, % Systematic error component, % Mercury 0.1 6 20 0.8 4 8 Table 2 Sample consumption per determination no more than 20 ml Reductant consumption per determination 1.0 ÷ 1.5 ml The generator is supplied with: spectral lamp for mercury; set of replacement parts; set of spare parts; guidelines for the determination of mercury; reagent (tin chloride); manual dispenser 10 ml.
