13 CRM Group - All rights reserved for all countries. Cannot be disclosed, used, or reproduced without prior written specific authorization of CRM Group - CONFIDENTIAL - Privileged Information - CRM Group proprietary information. Advantages of LIBS Chemical analysis at stand-off o distance from a few mm to > 100 metres o no contact with the target Ok for harsh environment: hot materials (>1500 C), radioactivity, explosives...

14 CRM Group - All rights reserved for all countries. Cannot be disclosed, used, or reproduced without prior written specific authorization of CRM Group - CONFIDENTIAL - Privileged Information - CRM Group proprietary information. Other advantages of LIBS Works on a large variety of materials o solids, liquids, gases o conductors (metals, ), insulators (ceramics, ) o materials with complex composition Very fast o Qualitative analysis in a few nanoseconds (1 single shot) o Quantitative assessment in a few seconds Ok for moving products No (or limited) need for surface preparation In-depth gradients by multiple laser pulses 9de Sensor for Food Gebruikersgroep vergadering, IMEC, 2 dec

15 CRM Group - All rights reserved for all countries.
