DF-170 OES

详情

The DF***0 OES is mainly used for analysis up to 3 metal matrix composites. Digital light source with customizable excitation parameters is available for various metals, enabling more stable analysis.
 

• Brand-new standardized module design; highly-intergrated circuit; independent charging system;
• All exit slits are on one belt with easy addition if needed.
• Parts with high quality: core parts from the world well-known manufacturers.
• Oil backstreaming prevention is achieved by creating a vacuum environment in the optical chamber, making no vaporized oil come through. A computer-controlled vacuum pump enables its working time less than 5% of the total DF***0 working time, largely extending the pump life.
• A built-in light reduces the dark current in PMT to a great extent, which results in an improved S/N and an extended life of PMT (*8mm in diameter).
• Custom working curves can be made, coupled with special calibration software tofend off spectral and background interference. This will cut the effects of metals metallurgical history and improve their analytical outcome.
• Highly-precise thermostatic system can keep the range of temperature fluctuation between *0.2℃ and *0.2℃.
• Automatic plotting technology is applied to optical calibration to position smartly the entrance slit.
• User-friendly operational software with multiple language versions under WINDOWS operating system.
• The multipurpose operational software can meet your various needs by displayingelementaldata in a flexible way and supporting various printing formats.
• ****0s of analytical process
