Fischer Presents the Next Generation of Digital Pulse Processors

Fischer Presents the New DPP+

The new in-house developed pulse processor DPP+

Helmut Fischer Global has developed its instruments for improved performance with new digital pulse processors (DPP+). Developed in-house, the processor combines Fischer measurement technology with the latest technological advancements. Used together with the new large silicon drift detector (SDD), a higher count rate is achieved with excellent energy resolution. This results in shorter measurement times at equal or higher measurement repeatability.

X-ray fluorescence spectrometers used for gold applications (Goldscope SD 520 and SD 550 and Fischerscope X-RAY XAN 220 to 252) are the first instruments to benefit from the new DPP+ installation. The DPP+ is able to process fluorescence signals at a much faster speed compared to its predecessor. At the same time, the large SDD with an effective area of 50 mmยฒ is able to detect more fluorescence signals than before. Together, these two components bring Fischer X-ray fluorescence spectrometers to a new level of precision.

Thorough testing shows that the absolute standard deviation can be reduced by up to 45 percent at the same measurement time with the new DPP+ and large SDD. Moreover, the same standard deviation is achievable with a measurement time that is three times shorter.

By developing components in-house, Fischer ensures the high quality of each measuring device. In this manner, Fischer maintains its position as the leading measurement technology specialist worldwide.
