Instrument Introduction

The OSA100 XRF slurry current analyzer is a large-scale online grade monitoring analyzer that integrates optical, mechanical, and electrical components. It can be widely used in industries such as non-ferrous metals, metallurgy, and mineral processing. The product has significant characteristics such as high degree of automation and intelligence, stable and reliable operation, fast and accurate analysis, and convenient operation and maintenance. The system adopts a modular design concept, highly integrated functions, compact structure, wide range of channel capacity expansion, which can meet the analysis needs of mining users of different scales, and can also participate in process automation control.

Performance characteristics
High degree of automation and intelligence
The system realizes computer automation control of sampling, measurement analysis, daily sampling, and data processing operations. And it adopts pneumatic electronic control technology, which ensures reliable system operation, simple maintenance, and no environmental pollution. The workstation system has powerful functions, high intelligent programs, remote data publishing capabilities, and a fault self diagnosis and error reporting mechanism.
Analyze stability and reliability
The long-term drift of the instrument can be automatically compensated by monitoring the measured values of the standard samples. Moreover, the instrument also has a "linearization correction" function, greatly improving the adaptability of analytical mathematical models and ensuring the accuracy of analysis.
The sample has sufficient representativeness, freshness, and fast and accurate analysis
By using methods such as fluid cross-section sampling and gap sampling, the slurry sample box adopts jet technology to ensure that the samples have sufficient representativeness and freshness, and can truly reflect the actual situation of the process. Calibration sampling can take out two parallel samples at once, ensuring the accuracy and reliability of sampling.
In addition, under normal operating conditions, the system can provide analysis results for 12 flow channels within 12-13 minutes, which is fast and can guide production. Using traditional manual sampling laboratory analysis, due to the serious time lag effect, operators cannot timely obtain the status and trend of the production process, which cannot guide production.
Safe and radiation free
The unique fully enclosed optical channel structure design ensures that there is no radiation within the range that the human body may be exposed to during operation and maintenance. Moreover, the instrument has mechanical and electronic safety interlock mechanisms to prevent accidental injury to the human body. In addition, the instrument uses an X-ray tube as the excitation source, and there is no risk of recovery, storage, or fire caused by isotopic radiation sources. In addition, when the sample box is in an empty state, the special structure scatters X-ray radiation to a negligible level.
Easy operation and maintenance
The system adopts modular design, with high functional integration, small size, and easy operation and maintenance; The system adopts pneumatic and electronic control working mode, which is stable, reliable, pollution-free, and easy to maintain. In addition, the system achieves computer automation, intelligent control and management, with minimal or no daily maintenance required.
