Acid Chemical Analyzer (Multi-Element Rapid Analyzer) / GKF-VIII
Won the SME Technology Innovation Fund of the Ministry of Science and Technology
I. Overview: The GKF series silicate component rapid analyzer is aimed at the silicate industry for a long time. The process of chemical analysis of materials using gravimetry, volumetric method, spectrophotometry, flame photometry and atomic absorption spectrometry has a long process, which can not meet the production requirements. Developed for process control requirements.The complete analysis of a sample can be completed within a few hours, and its analysis accuracy meets or exceeds the requirements for analytical accuracy in national standards for analytical methods of silicate materials.It has significant advantages in the field of silicate system analysis, especially suitable for quantitative analysis of non-metal industries such as ceramics, refractories, cement, glass and non-ferrous metals such as tungsten, molybdenum, nickel, cobalt, copper and smelting industries.This product has been widely used in colleges, scientific research institutes, factories and mining enterprises. The company has been producing since the 1990s, and now has more than a thousand instruments serving universities, scientific research units, quality inspection departments, daily-use and building ceramics factories, Electric porcelain factory, ceramic raw material factory, glaze factory, refractory material, glass, non-ferrous metal and smelting industry have accumulated rich experience in production and field service. It was fully upgraded to GKF-V type in March 2008 (the same year won the National Ministry of Science and Technology Innovation Fund) Fully upgraded to GKF-VI type in June 2010 Fully upgraded to GKF-VII type in December 2011
Fully upgraded to GKF-VIII type in December 2014
3. Working principle and characteristics: GKF series silicate composition rapid analyzer is based on photometric analysis. By using micro-current scale to the left and photocurrent scale to the right, a wide range of linearization is achieved, which avoids large concentrations in photometric analysis Defects of the solution deviate from Beer's law, linear difference, and large analysis error.In this analysis method, a stable, fast and accurate color rendering system and system analysis process are adopted, and a unique linear expansion and sensitivity improvement method is adopted. For the problem of poor content sensitivity, the analysis results are accurate and reliable.The analysis process is as follows: sample preparation, weighing and melting, leaching and color development, measurement data, processing results, printout, and analysis results. 1. A new type of photometric analyzer developed based on the principle of photometric analysis.Especially suitable for the systematic analysis of silicate chemical composition. 2. Adopting advanced technology can maintain excellent linear accuracy in high concentration range.The instrument has good stability and reproducibility, and is especially suitable for fast analysis on site. 20个样品）。3. The computer data processing system is adopted, which is more suitable for the joint measurement of multiple samples (up to20samplescan be determinedatatime). WINDOWS风格，界面美观，功能强大，操作简单方便。4. Specialized in the development of independent intellectual property analysis software, standardWINDOWSstyle, beautiful interface, powerful, simple and convenient operation. 5. GKF-VIII is a new series of research results, all switches and knobs on the original instrument are cancelled, all functions are realized by software, automatic zero adjustment and automatic correction.It fundamentally avoids the occurrence of mechanical failure, greatly improves the stability of the instrument, and the operation is simpler.Basically, it can achieve zero faults and zero maintenance.。Automatic aspiration. 6. GKF-VIII silicate component rapid analyzer software is richer, stronger anti-interference ability, better test method and reliability.3元素同步测量系统、自动数据处理系统，优化分析方法。Equipped with an automatic precise dosing system, a3-element synchronous measurement system, and an automatic data processing system to optimize the analysis method.The number of special reagents is greatly reduced, the customer's consumables market is expanded, and the analysis cost is greatly reduced.
