BDHg-60 direct injection mercury measuring instrument
Introduction: The BDHg-60 direct sample mercury measuring instrument adopts the principle of electric heating, evaporation and cold atomic absorption, without adding any reagents, and without complicated and tedious sample pretreatment. It directly measures the total mercury in solid and liquid samples, effectively avoiding sample pretreatment. The process brings about problems such as mercury loss, cross-contamination and environmental pollution, which ensures the accuracy of the analysis data and saves time, labor and reagents. The application of BDHg-60 direct sample mercury measuring instrument meets the standards of HJ 923-2017, HJ 910-2017, GB/T 31947-2015, EPA7473 and SN/T 4697-2016. Mainly used in food safety, environmental protection, disease control, medicine and medical treatment, agriculture, geology and minerals, soil, surface water and groundwater, cosmetics, teaching research and other fields of mercury content detection. Features 1. The operation is simple and convenient: the sample does not need to be digested, the experimenter only needs to weigh the sample and place it on the autosampler. The software can directly read the weighing data and click "Run" to complete all measurements; 2. The sample analysis efficiency is high: the test of a single sample of complex matrix is less than 5 minutes, and the test of a single sample of simple matrix is less than 3 minutes. Up to 60 samples can be placed at one time, and special samples can be inserted or deleted at any time; 3. Better repeatability and accuracy: the design of special high-efficiency catalytic tubes and gold traps ensures the accuracy of the test results; the patented rapid condensation device makes the system more effective in removing water and has a smaller mercury memory effect , The test repeatability is better; 4. The detection process is green and environmentally friendly: the whole analysis process does not need to use toxic and harmful chemicals, and the exhaust gas generated during the analysis process is effectively absorbed by the exhaust gas treatment device; 5. Intelligent work platform: simple software operation, method file library, system self-diagnosis, self-detection of fault points, real-time display of all spectra, full temperature monitoring, one-click update of the latest embedded programs; 6. The instrument uses LAN/WFI communication interface: to ensure fast communication and reliable and stable operation of the system. Technical index: Quality detection limit: ≤0.005ng; Repeatability: RSD≤1%(1ng); Larger sample volume: 600mg for solid and 1.0mL for liquid; Linear range: 0~40ng (long absorption pool); 40~1000ng (short absorption pool); Measurement method: adopt peak area or peak height method; Calibration method: standard solution or standard substance; Autosampler: Built-in autosampler for direct injection of solid/liquid samples; it can be upgraded to configure an independent sealed automatic liquid sample injector that prevents the volatilization of liquid samples;
