Rapid analyzer for chemical composition of silicate (multi-element rapid analyzer)

Overview

EA-CR series silicate composition rapid analyzer is designed for the silicate industry that has long used gravimetric method, volumetric method, spectrophotometric method, flame photometric method and atomic absorption photometric method to combine chemical analysis of materials. The process is long and cannot meet the needs of production. Developed to meet process control requirements. A complete analysis of a sample can be completed within a few hours, and its analytical accuracy meets or exceeds the analytical accuracy requirements of the relevant national analytical method standards for silicate materials. It has significant advantages in the field of silicate system analysis, and is especially suitable for quantitative analysis in non-metal industries such as ceramics, refractories, cement, and glass, as well as non-ferrous metals such as tungsten, molybdenum, nickel, cobalt, and copper, and in the smelting industry. This product is widely used in colleges and universities, scientific research institutes, factories and mines. Our 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 construction ceramics factories, It has accumulated rich production and on-site service experience in electric porcelain factories, ceramic raw material factories, glaze factories, refractory materials, glass, non-ferrous metals and smelting industries.

In March 2008, it was fully upgraded to EA-CR-V type (won the Innovation Fund of the National Ministry of Science and Technology in the same year)

Comprehensive upgrade to EA-CR-VI in June 2010

Comprehensive upgrade to EA-CR-VII in December 2011

Comprehensive upgrade to EA-CR-VIII in December 2014

Working principle and characteristics:

EA-CR series rapid silicate composition analyzer is based on photometric analysis. By using microcurrent to expand the scale to the left and photocurrent to expand the scale to the right, it achieves a wide range of linearization and avoids large concentrations in photometric analysis. The solution deviates from Beer's law, has poor linearity, and causes large errors in analysis results. In this analysis method, a stable, fast and accurate color development system and systematic analysis process are adopted, and a unique method of linear expansion and sensitivity improvement is adopted to solve the problem that ordinary photometric methods will deviate from the linearity when analyzing high component content, and when analyzing low component content, The problem of poor content sensitivity, the analysis results are accurate and reliable. The analysis process is: sample preparation, weighing the melted sample, leaching and color development, measuring data, processing results, printing output, and analyzing the results.

1. A new photometric analyzer developed based on the principle of photometric analysis. Especially suitable for systematic analysis of chemical components of silicate.

2. Using advanced technology, excellent linear accuracy can be maintained in the high concentration range. The instrument has good stability and reproducibility, and is especially suitable for rapid on-site analysis.

3. Using a computer data processing system, it is more suitable for joint testing of multiple samples (up to 20 samples can be measured at one time).

4. Specially developed analysis software with independent intellectual property rights, standard WINDOWS style, beautiful interface, powerful functions, simple and convenient operation.

5. The EA-CR-VIII model is a new series of research results. All switches and knobs on the original instrument have been cancelled. All functions are realized by software, with automatic zero adjustment and automatic adjustment and correction. It fundamentally avoids the occurrence of mechanical failure, greatly improves the stability of the instrument, and makes the operation simpler. Basically, zero failures and zero maintenance can be achieved. Automatically aspirate samples.

6. The EA-CR-VIII silicate composition rapid analyzer has richer software, stronger anti-interference ability, and better testing methods and reliability. Equipped with an automatic and precise liquid adding system, a 3-element synchronous measurement system, an automatic data processing system, and an optimized analysis method. The variety of special reagents has been greatly reduced, the market for customer consumables has expanded, and the cost of analysis has been greatly reduced.
