Beijing Zhongye Yiyuan Technology Co., Ltd. is a professional manufacturer of Inductively Coupled Plasma Emission Spectrometer (ICP-AES/ICP-OES), and a high-tech enterprise integrating scientific research, production, sales, and technical services. The company has a group of professional personnel who have been engaged in ICP spectrometers for a long time in China, with strong technical strength, excellent testing methods, advanced production processes, and a complete quality assurance system. The ICP-7911 inductively coupled plasma atomic emission spectrometer developed by our company has been improved on the basis of its years of practical experience in ICP spectroscopy, making its performance more perfect. The high-voltage power supply circuit of the RF generator adopts advanced electronic switch circuit technology, eliminates bulky step-up transformers and high-frequency resistive coils, and adopts power closed-loop feedback technology. The ICP spectrometer with high precision and sensitivity has unique advantages such as fast analysis speed and high stability. Due to the adoption of computer technology, the intelligence of the instrument, the collection and processing of images, texts, and data displayed on the screen have reached the current advanced level in China, making it an ideal analytical instrument for many industries. With the development concept of "quality first, service first", we provide high-quality and sincere services to our customers. ICP spectrometer, as a large precision analytical instrument, is widely used in rare earth, precious metals, alloy materials, medicine and health, metallurgy, geology, petroleum, chemical industry, commercial inspection, environmental protection, as well as scientific fields such as neodymium iron boron, silicon, ferrosilicon, tungsten, molybdenum, and higher education institutions for element quantitative analysis, and is highly praised by users. In order to better meet market demand, it is a high-tech product that integrates optical, mechanical, electrical, computer, and analytical technologies. It has the characteristics of fast testing speed, wide measurement range, and accurate and reliable analysis results. In addition, the company has independently developed an intelligent temperature controlled cooling circulating water tank, model ZY-2600, which provides cooling protection for ICP spectrometer, ICP-MS, X-ray fluorescence spectrometer, scanning electron microscopy and graphite furnace atomic absorption spectrometer. The company has also developed a series of spectral products and accessories such as high-frequency infrared carbon sulfur analyzer, atomic absorption spectrophotometer, spark direct reading spectrometer, etc., expanding the company's products and services to a wider range of industries and enabling qualitative or quantitative analysis of test samples from ultra trace to constant.
