QSG750-Ⅱ型真空直读光谱仪

QSG 750-II火花发射光谱仪也可以称为OBLF的旗舰机型。该单或多矩阵模型对于要求zei低可能检测限，zei高重现度和关于分析物的额外冶金信息的所有应用都是理想的。应用范围从主要生产商，如钢铁厂或其他冶炼厂通过金属加工公司直到研究机构和大学。

QSG 750-II与QSN 750-II型号相当，主要区别在于数据记录系统，它是基于OBLF开发的GISS技术（单点火焰门控集成）。具有相同的尺寸，它还配有经过测试的硬件组件，如温度稳定的750 mm真空光学元件，具有自由定义参数的门控数字源（GDS）技术和zl的自清洁火花支架。排气过滤器确保消耗的氩气被清除。所有关键设备部件的易于访问简化了用户需要执行的服务任务。

More Infos

The QSG 750-II uses the GISS (Gated Integration of Single Sparks) data logging system, developed by OBLF. In combination with logging and online processing of the single spark intensities of all measuring channels, time-resolved spectroscopy gives rise to many additional applications.

Single spark spectrometry (or PDA – pulse distributed analysis), for instance, provides critical information about the microscopic composition of the sample. In this respect, key words are the detection of inhomogeneous samples, differentiation between dissolved and undissolved components (e.g. aluminium in steel) as well as the detection and determination of inclusions. To ensure best possible use can be made of these options, the OBLFwin software not only includes all standard functions (materials control, automatic program selection, etc.), but also provides additional features that permit simple definition of parameters when a bad sample is detected or when analysing inclusions. All the single spark data can be made available for export to other computer systems.

Time-resolved spectroscopy can reduce spectral interference and substantially improve the detection limits of many elements in comparison to standard spectrometers. This opens up completely new avenues when analysing pure metals.

All of the QSG 750-II model’s many functions are available for manual and automated operation, as many applications have shown in the steel industry in particular. In such cases, sample handling is performed by a robot and the counter-electrode is cleaned by a special unit fitted to the spark stand. The measured values are automatically transferred to superordinate systems using a network connection. Integrated software modules control and monitor the functionality of the spectrometer. These functions also include analysing control and recalibration samples.

Precise instructions on how to operate the QSG 750-II model and use the software are naturally given during installation. The customer only has to ensure availability of a power and an argon supply.
