Spark optical emission spectrometer / laboratory / for metal analysis

The QSG 750 spark emission spectrometer represents OBLF?s flagship model. This single- or multi-matrix model is ideal for all applications demanding the lowest possible detection limits, the highest degree of reproducibility and additional metallurgical information about the analyte. The application spectrum goes from primary producers like steel mills or other smelteries through metal-processing companies right up to research institutes and universities.

At first glance, the QSG 750 is comparable with the QSN 750 model. The main difference to the other OBLF spectrometers lies in the data logging system, which is based on the GISS technology (Gated Integration of Single Sparks) 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. 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.
