Nanjing Mingrui Analytical Instruments Co., Ltd. AA2630 Daily-use Fine Porcelain Material Analyzer uses a PC to automatically control the instrument and process data, fully meeting all requirements of modern analysis. It can detect a variety of trace metal elements, including more than 70 elements such as lead, chromium, cadmium, copper, iron, calcium, magnesium, zinc, chromium, mercury, arsenic, and selenium. The detection accuracy of the instrument reaches the ppb level. Phone: 18651882886 (WeChat ID).
This model is equipped with the most convenient, reliable, and practical assistant software, fully supporting the Windows system platform. With simple man-machine dialogue, powerful data analysis and processing functions, and convenient and fast data output functions, it ensures the accuracy and reliability of the results. The integrated structural design of the flame atomizer and the graphite furnace atomizer allows for automatic switching between the two; the eight-lamp automatic switching turret automatically adjusts the power supply and optimizes the beam position, and pre-sets the working conditions of the hollow cathode lamp for easy multi-element detection; automatic flow setting, automatic ignition, and automatic flameout protection; automatic adjustment of negative high voltage and lamp current.
It automatically switches the spectral bandwidth, with 0.1, 0.2, 0.4, 1.0, and 2.0nm (five automatic options), automatically controls wavelength scanning, automatically searches for peaks, and features international-level full-band fast scanning and positioning. It completes automatic zero adjustment within 30 seconds, automatically sets the gas flow, and automatically selects the fuel-to-oxidant ratio for element analysis. The advanced and reliable safety protection system comprehensively protects the safety of operators. The reliable position recognition system monitors the cooling water flow, flame, and abnormal pressure in real-time, ensuring both the safety of the machine and the safety of operators. In case of an accident, water, electricity, and gas will be automatically shut off. It can be optionally equipped with a hydride generator. The high-quality optical system features a suspended design, and vibrations and changes in environmental temperature do not affect the stability of the instrument. It has strong light energy and extremely high stability. The newly designed flame atomizer and the ultra-high-sensitivity graphite furnace automatically optimize the temperature-rising program through PC control within the whole process range, and the high stability of the heating power further improves the reliability of the analysis values.
