德国IPI GAM3000过程四级杆质谱仪在钢铁转炉气体分析中的应用

red

     The GAM 3000 process gas mass spectrometer is most successfully deployed in the analysis of converter gas. By continuously monitoring converter waste gases it is possible to identify the current process status at any given time. The data provided by the GAM 3000 can be used to model the entire process. Hence the blowing cycle can be shortened and process disruptions prevented.   

      GAM 3000 过程气体质谱仪在转炉气体分析中的应用最为成功。通过持续监测转炉废气，可以识别任何给定时间的当前过程状态。GAM 3000 提供的数据可用于对整个过程进行建模。因此，可以缩短吹瓶周期并防止工艺中断。

典型测量数据:

序号	被测组分	测量能力	典型测量范围
1	H2	0-100%	0-1%
2	N2	0-100%	40-80%
3	CO	0-100%	0-90%
4	O2	0-100%	0-25%
5	Ar	0-100%	0-2%
6	CH4	0-100%	0-1%
7	CO2	0-100%	0-40%

     The GAM 3000 was developed by InProcess Instruments especially for steel applications.The main applications are converter gas and blast furnace analysis.The current process status can be determined at any time by continuous monitoring of the exhaust gases.  Corrections of the process conditions are possible immediately and the exact end point of a O2 blowing process can be precisely determined. The exhaust gas control system of the GAM 3000 can reduce the duration of a blowing cycle and prevent process disturbances.

   GAM 3000 由 InProcess Instruments 开发，专为钢铁应用而开发。主要应用是转炉煤气和高炉分析。通过对废气的连续监测，可以随时确定当前的过程状态。可以立即纠正工艺条件，并且可以精确确定 O2 吹扫工艺的确切终点。GAM 3000 的废气控制系统可以缩短吹扫周期的持续时间并防止工艺干扰。

四级杆质谱仪工作原理图   

      Mass spectrometer systems can be divided into a variety of technological categories. Quadrupole mass spectrometers are the most widespread systems because they perform very well. They also stand out due to their compact and robust construction.

    质谱仪系统可分为多种技术类别。四极杆质谱仪是最广泛的系统，因为它们的性能非常好。它们还因其紧凑而坚固的结构而脱颖而出。

    For mass separation, quadrupole systems use a high-frequency alternating electrical field. A Faraday cup and a secondary electron multiplier (SEM, Channeltron) serve as detectors.

    对于质量分离，四极杆系统使用高频交变电场。法拉第杯和二次电子倍增器（SEM，Channeltron）用作检测器。

   Quadrupole mass spectrometers allow fast measurements within milliseconds and offer a high dynamic range from the ppb to the percentage level. These systems can be optimised for specific application purposes, therefore providing an attractive price/performance ratio.

    四极杆质谱仪可在几毫秒内进行快速测量，并提供从ppb到百分比水平的高动态范围。这些系统可以针对特定应用目的进行优化，从而提供极具吸引力的性价比。
