The OBLF QSN 750-II instrument is a spark vacuum optical emission spectrometer with an optical system radius of 750 mm, which can be used as a single or multi-matrix . As a result, the spectrometer has a wide field of applications not only in the production of metal in industrial production, but also in testing materials in research institutes.
The integrating electronics and photomultipliers, selected according to customer specifications, are placed in an optical chamber, and thus protected from external influences. Thermally stabilized optics and a GDS digital pulse generator guarantee a high degree of signal reproducibility and analytical consistency. The design of the easily dismantled self-cleaning patented spark rack and optical chamber entrance window allows the user to maintain them without difficulty. Used argon is cleaned by a filter.
Unlike the "little brother" GS 1000-II , the QSN 750 optical emission spectrometer can also be used in an automated system. In this case, the device, working together with the sample preparation device and the robot arm, is equipped with an automatic system for cleaning the counter electrode. The results of the analyzes are transmitted to a subordinate computer system via a network connection. To ensure optimum quality control, the spectrometer measures control samples fed by the robot at regular intervals. The key to functioning is to constantly monitor and, if necessary, transfer this information to other systems.
When using multimatrix systems for a huge number of analytical problems, a large number of analytical programs may arise. For such complex systems , the spectrometer software , called OBLFwin, provides numbered stand-alone programs that fully meet the needs of the customer. In addition, there is an automatic program selection that makes it easy to assign the correct analysis program. Depending on the application - which material is being detected - the measured values appear on the screen approximately 16-30 seconds after the start of the measurement process and can be printed, transmitted over the network or processed later.
