HGA-100 direct injection mercury measuring instrument
Introduction: HGA-100 direct sample mercury measuring instrument is suitable for the determination of mercury content in samples in the fields of environmental protection, food safety, disease control, medicine, agriculture, geology and mining, metallurgy, cosmetics, soil, urban water supply and drainage, teaching and research. Features: Solid and liquid samples are directly injected for measurement without tedious pre-processing; 1. Principles of electrothermal evaporation and cold atomic absorption; 2. Temperature control in the whole process of cracking, catalysis, capture/release; 3. Constant temperature long and short absorption cells, suitable for samples with different contents; 4. Adopt solar-blind photomultiplier tube R7154 detector; 5. A 40-position autosampler, which can be connected to an electronic balance; 6. Multi-thread processing, embedded software design technology. Nano gold-plated quartz sand and high-efficiency catalysts and other technologies; 1. Full temperature control, eliminating mercury memory effect, light scattering and background interference; 2. High-stability low-pressure mercury lamp, and energy automatic balance technology, supplemented by narrow-band filters, overcome the drift of the light source and eliminate the influence of stray light; 3. Weighing data can be directly transmitted to the data processing system to eliminate errors caused by human factors and improve detection efficiency; 4. According to the absorbance intensity of the sample, the standard curve data of the long and short cells are automatically selected for quantitative calculation. Technical index: Sample detection limit: <0.005ng Relative standard deviation (RSD): <2.0% (1ng) Correlation coefficient (r):> 0.997 Maximum injection volume: 0.50g (solid) 1.00mL (liquid) Linear range: 0 ~ 30ng (long absorption pool) 30 ～ 200ng (short absorption pool) Typical analysis time: 5min
