- Inline / at-line analyzer with laser class 1 housing
- Qualitative and quantitative analysis
- Non-contact, almost non-destructive
- Measurement duration < 1 s/point
- 24/7 operational mode possible
Setup
The PAnalyzer (Panel Analyzer) has especially been developed for the fast and contact-free quality control of large-area samples in industrial production lines. Spatially resolved analysis of the lateral element homogeneity is provided by means of laser-induced breakdown spectroscopy (LIBS) applied to a motorized XY measuring head.
Short pulse laser radiation is focused on the sample surface and generates a light emitting plasma. The chemical elements contained in the material provide a characteristic emission line spectrum similar to a fingerprint, which is simultaneously detected with a single measurement by the applied high-resolution ARYELLE echelle spectrometer. Multi-elemental evaluation is automatically performed by operating and analysis software Sophi. By adding a Raman module, the molecular composition of samples can be determined.
The PAnalyzer provides a 24/7 operational mode for industrial use, laser class 1 housing, door interlock and online video monitoring. Several modular components like laser, spectrometer-detector unit and sample holder are individually customized for the designated application. The industrial PC with software Sophi features an easy to use script-based automation, remote control and remote maintenance. Ethernet is the major interface for a proper communication with existing industrial devices.
