[China Instrument Network Instrument R&D] Electromagnetic radiation is the phenomenon in which electromagnetic waves propagate around the electromagnetic wave during electromagnetic vibration. Long-term electromagnetic radiation will cause great harm to the human cardiovascular system, visual system, nervous system and reproductive system. It is a major cause of cardiovascular disease, cancer mutation, infertility, and cataract. The principle of the arc emission spectrometer is to generate high-power arc flames through high-frequency ignition, to achieve evaporation and excitation of the sample, and to carry out the determination of each element. Therefore, long-term use of the instrument of the arc emission spectrometer is seriously endangered by electromagnetic radiation, and it is necessary to do a good job of shielding the electromagnetic radiation of the arc emission spectrometer. It is also an embodiment of the sense of responsibility of the instrument manufacturer to the customer.
E5000 full spectrum direct reading arc emission spectrometer radiated disturbance field strength test report
The E5000 full-spectrum direct-reading arc emission spectrometer produced by Concentration Technology (Hangzhou) Co., Ltd. is the first full-spectrum direct-reading emission spectrometer for non-metallic powder element analysis in China. It uses an arc excitation light source and a Paschen-Runge type full spectrum CCD. The spectrometer is combined with the laser positioning and programmable electrodes to automatically adjust the electrode position to achieve precise control of the excitation distance. The full spectrum information of the excited sample is obtained by high-array CCD data acquisition, and the analysis result is directly obtained by subtracting background and interference correction in real time. . Compared with the traditional spectrograph, the instrument has simple operation, high automation, rich spectral line information, and rapid and accurate measurement results.
E5000 adopts a new generation digital arc light source, which replaces the traditional arc source. The electrode is fully aligned and excited in the moment room. It eliminates the need for manual direct observation of the adjustment distance, effectively protects the human eye, and shields a large amount of electromagnetic radiation. In addition, the digital power supply is smaller in size. , can be directly placed inside the instrument, without the need to extend the excitation line to connect the external AC power supply, effectively reducing the radiation generated during the conduction of large currents.
The radiation test results show that, during normal work, if the arc light source has no protective measures, the electromagnetic radiation is significantly higher than the 40 dBN defined by the national standard; if the electromagnetic radiation of the power supply is effectively shielded, when the long excitation line is used for excitation, the high frequency is above 300 MHz. Electromagnetic radiation is slightly reduced, but electromagnetic radiation below 300 MHz is still large. The fully protected E5000 instrument is significantly reduced in electromagnetic radiation during normal operation, in full compliance with the electromagnetic radiation limit requirements for instrumentation equipment in the national standard.
