Comparison between intensified CCD and non-intensified gated CCD detectors for LIPS analysis of solid samples

摘要

We have carried out a performance comparison between spectrometer/ICCD and spectrometer/ non intensified gated CCD systems in terms of spectrochemical analysis of four elements in aluminum alloy samples. The results show that the ICCD detector affords significant advantages in terms of spectral resolution, intensity, dynamic range and sensitivity. However for applications which do not require high resolution or high sensitivity (in the range of 100 ppm) the non intensified gated CCD/spectrometer seems to be an appropriate choice for low cost LIPS instrumentation.
